I have installed Jupyter on Windows 10, Python 3.x via
$ pip install jupyter
The installation works fine, even though I did restart the terminal.
But trying to run
$ jupyter notebook
gives the following error
'jupyter' is not recognized as an internal or external command, operable program or batch file.
How and where do I find the executable for Jupyter?
If you are absolutely sure that your Python library path is in your system variables (and you can find that path when you pip install Jupyter, you just have to read a bit) and you still experience "command not found or recognized" errors in Windows, you can try:
python -m notebook
For my Windows at least (Windows 10 Pro), having the python -m is the only way I can run my Python packages from command line without running into some sort of error
Fatal error in launcher: Unable to create process using ' "
or
Errno 'THIS_PROGRAM' not found
Please try either of these commands first;
$ py -m notebook
$ python -m notebook
for jupyterlab users
py -m jupyterlab
Otherwise
$ python -m pip install jupyter --user
$ jupyter notebook
If this does not work.
pip does not add jupyter directly to path for local.
The output from
$ which python
/c/Users/<username>/AppData/Local/Programs/Python/Python35-32/python
After some digging I found a executable for jupyter in the folder:
C:\Users\<username>\AppData\Roaming\Python\Python35\Scripts\jupyter.exe
Difference between local and roaming folder
So if you want to be able to execute a program via command line, you need to add it into the %PATH variable. Here is a powershell script to do it. BE SURE TO ADD THE ";" before adding the new path.
$ [Environment]::SetEnvironmentVariable("Path", $env:Path + ";C:\Users\<username>\AppData\Roaming\Python\Python35\Scripts", [EnvironmentVariableTarget]::User)
Update:
if you are using python3, switch out python with python3
but I encourage you to use pyenv instead :)
I had the exact same problem and it was driving me crazy. Other answers provide a solution, but they don't explain why you and I are having this problem.
I will try to explain why this is happening and then provide some solutions.
You can go to the end to see the TL;DR.
1)What's going on? Why is this error happening?
I'll try to make a step-by-step answer so everything is explained clearly.
If you think it's too basic at the beginning, go to the end of this "article".
I'll first start with common things like running the python shell from the terminal or running pip. You'll see why you can do that from the terminal and we'll end up on why and how you can run the jupyter notebook from the terminal as well.
Ready? Let's start!
Have you ever wondered why you can type python in the terminal (command prompt) and suddenly start the Python interpreter?

You probably already know (but maybe don't) that this is because Python was added to the Windows PATH environment variable. You probably did it at installation time or afterwards.
But, what is this PATH environment variable?
It basically allows you to run any executables, that are located inside
the paths specified in the variable, at the command prompt without
having to give the full path to the executable.
You can check the content of that PATH variable with:
>>> import sys
>>> for path in sys.path:
print(path)
C:\Users\YOUR-USERNAME\AppData\Local\Programs\Python\Python39\python39.zip
C:\Users\YOUR-USERNAME\AppData\Local\Programs\Python\Python39\DLLs
C:\Users\YOUR-USERNAME\AppData\Local\Programs\Python\Python39\lib
C:\Users\YOUR-USERNAME\AppData\Local\Programs\Python\Python39
C:\Users\YOUR-USERNAME\AppData\Local\Programs\Python\Python39\lib\site-packages
... (some other paths were taken out for clarity)
You can see this folder: C:\Users\YOUR-USERNAME\AppData\Local\Programs\Python\Python39. This is the place where Python version 3.9 is installed. Let's check its content:
<DIR> DLLs
<DIR> Doc
<DIR> etc
<DIR> include
<DIR> Lib
<DIR> libs
<DIR> Scripts
<DIR> share
<DIR> tcl
<DIR> Tools
LICENSE.txt
NEWS.txt
python.exe
python3.dll
python39.dll
pythonw.exe
vcruntime140.dll
vcruntime140_1.dll
Voilà! We have the python.exe file (an executable). We have a Python executable file in the PATH, that's why you can start the Python interpreter from the terminal with just typing python. If this wasn't the case you would have to type the full path to the executable file in the terminal:
C:\Users\YOUR-USERNAME> C:\Users\YOUR-USERNAME\AppData\Local\Programs\Python\Python39\python)
Instead of just:
C:\Users\YOUR-USERNAME> python
And what about when you use pip?
It's the same principle. You can run pip from the terminal because there is a pip executable file in the PATH variable.
If you go to C:\Users\YOUR-USERNAME\AppData\Local\Programs\Python\Python39\Scripts\ (which is in the PATH showed above) you'll see many executables files. One of them is pip. Actually I have three versions: pip, pip3.9 and pip3.
The Scripts folder allows exectuable files to be run from the terminal. Like pip or other libraries that you intend to run directly from the terminal. The Scripts folder:
...is not intended for you, it's for scripts that are installed as
components of modules that you install. For example, pip is a module,
but it also has a wrapper script by the same name, pip, which will be
installed in that directory.
If you put something there and it is properly in your PATH, then it
should be executable
That wrapper script would be the pip executable file. When this executable file is run, it locates the pip folder in the Python installation folder and runs pip.
But you could also run pip directly from the installation folder (C:\Users\YOUR-USERNAME\AppData\Local\Programs\Python\Python39\Lib\site-packages), without needing the executable pip file.
But, how can you do it?
I'm glad you ask. There is a Python way to run modules as the main module (without the need to import it).
python -m pip
When you run a module directly its name becomes __main__. What -m does is:
Search sys.path for the named module and execute its contents as the __main__ module.
What is __main__?
'__main__' is the name of the scope in which top-level code executes.
A module’s __name__ is set equal to '__main__' when read from standard
input, a script, or from an interactive prompt.
...
I guess that the pip executable does something similar, or at least, has the same effect: to start pip.
2)What does this have to do with the Jupyter Notebook?!
Think of the Jupyter Notebook as the same as pip. If you want to run jupyter in the terminal, you need an executable that it's on the PATH.
We have already seen that the executables of modules like pip or jupyter are located here C:\Users\YOUR-USERNAME\AppData\Local\Programs\Python\Python39\Scripts\.
If I check the content of the folder I see this:
easy_install-3.9.exe
easy_install.exe
f2py.exe
jsonschema.exe
jupyter-bundlerextension.exe
jupyter-console.exe
jupyter-nbconvert.exe
jupyter-nbextension.exe
jupyter-notebook.exe
jupyter-qtconsole.exe
jupyter-serverextension.exe
jupyter-trust.exe
pip.exe
pip3.9.exe
pip3.exe
I see the already mentioned pip, pip3.9 and pip3. But I don't see jupyter (the word "jupyter" alone).
If I type jupyter in the terminal I get the error that started all:
'jupyter' is not recognized as an internal or external command, operable program or batch file.
Finally we've reached an answer to your question!!!
'jupyter' is not recognized as a command because there is no executable file in the Scripts folder called jupyter.
So, let's try a different executable. What about jupyter-notebook?
BINGO! The notebook is running!
Serving notebooks from local directory:
C:\Users\YOUR-USERNAME\AppData\Local\Programs\Python\Python39\Scripts
Jupyter Notebook 6.3.0 is running at:
http://localhost:8888/?token=... (edited)
or http://127.0.0.1:8888/?token=... (edited)
Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
I don't know why I don't have a jupyter executable called 'jupyter'. The official documentation says to use jupyter notebook on the terminal, but it seems that in some cases it doesn't work. And I think it has to do with what I mentioned above: there is no jupyter exectuable in the Scripts folder.
If you remember, I told you that you can run pip as the main module using python -m pip.
It happens that you can do the same with jupyter.We just need to know how to call it. As in with pip, we have to check the folder where 3rd party libraries are installed: C:\Users\YOUR-USERNAME\AppData\Local\Programs\Python\Python39\Lib\site-packages.
You'll see jupyter_console, but this just creates an interactive notebook in the terminal, not exactly what you were looking for. You're also going to find folders ending with .dist.info, like jupyter_console-6.4.0.dist-info. This is just metadata of the Wheel Binary Package builder. You'll also see a folder like jupyterlab_pygments, but that's for JupyterLab. We want to use the classic Jupyter notebook.
What we want is to run notebook. How do we know this?
You'll see in the folder site-packages the folder (package) notebook. Inside there is a file called __main__.py:
#__main__.py
if __name__ == '__main__':
from notebook import notebookapp as app
app.launch_new_instance()
It's calling notebookapp.py which is a "A tornado based Jupyter notebook server." Yes, this is what we need.
We can see that launch_new_instance in the notebookapp calls launch_instance(), which "launches an instance of a Jupyter Application".
Perfect! We are in the correct folder. To run the jupyter notebook from the Python interactive shell we have to run the notebook package with:
python -m notebook
3)*** SUMMARY: SOLUTION ***
tl;dr:
I have explained and showed why this error is happening.
Now let's summarize the solutions:
To know the name of the jupyter executable (in the Scripts folder), so you can run directly from the terminal (Command Prompt) as:
jupyter notebook
or as:
jupyter-notebook
Or whatever name you have.
Run the notebook as the main module from Python:
python -m notebook
I hope this helps you as much as it helped me. I'm open to your comments and suggestions.
I had the same problem, but
py -m notebook
worked for me.
I got Jupyter notebook running in Windows 10. I found the easiest way to accomplish this task without relying upon a distro like Anaconda was to use Cygwin.
In Cygwin install python2, python2-devel, python2-numpy, python2-pip, tcl, tcl-devel, (I have included a image below of all packages I installed) and any other python packages you want that are available. This is by far the easiest option.
Then run this command to just install jupyter notebook:
python -m pip install jupyter
Below is the actual commands I ran to add more libraries just in case others need this list too:
python -m pip install scipy
python -m pip install scikit-learn
python -m pip install sklearn
python -m pip install pandas
python -m pip install matplotlib
python -m pip install jupyter
If any of the above commands fail do not worry the solution is pretty simple most of the time. What you do is look at the build failure for whatever missing package / library.
Say it is showing a missing pyzmq then close Cygwin, re-open the installer, get to the package list screen, show "full" for all, then search for the name like zmq and install those libraries and re-try the above commands.
Using this approach it was fairly simple to eventually work through all the missing dependencies successfully.
Cygwin package list
Once everything is installed then run in Cygwin goto the folder you want to be the "root" for the notebook ui tree and type:
jupyter notebook
This will start up the notebook and show some output like below:
$ jupyter notebook
[I 19:05:30.459 NotebookApp] Serving notebooks from local directory:
[I 19:05:30.459 NotebookApp] 0 active kernels
[I 19:05:30.459 NotebookApp] The Jupyter Notebook is running at:

In Python 3.7.6 for Windows 10. After installation, I use these commands.
1. pip install notebook
2. python -m notebook
OR
C:\Users\Hamza\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.7_qbz5n2kfra8p0\LocalCache\local-packages\Python37\Scripts
.
For my pc python-scripts are located in the above path. You can add this path in environment variables. Then run command.
1. jupyter notebook
You can add the following to your path
C:\[Python Installation path]\Scripts
e.g. C:\Python27\Scripts
It will start working for jupyter and every other pip install you will do here on.
Check whether you have given python PATH in environmental variables properly.
If not, then set python path. Then use:
$ python -m notebook
If you are using the Anaconda distribution, make sure when installing it that you check the "Change PATH" option.
first you should make sure that you are put your python path in your system variables ..
Then try run this
python -m pip install jupyter --user
and then
run this
py -m notebook or jupyter notebook
In Windows 10 you can use ipython notebook. It works for me.
I added
c:\users\[user]\appdata\roaming\python\python37\site-packages
to the path and it worked.
## windows CMD
for default install (just check "add path" and "next" when installing)
python -m notebook
for custom install in C:\
jupyter notebook
Problem for me was that I was running the jupyter command from the wrong directory.
Once I navigated to the path containing the script, everything worked.
Path-
C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\Scripts
I have two python version installed:
1. Python 3.8.2: This was installed independently
2. Python 3.7.6: This was installed along with Anaconda 3
Multiple versions caused conflict even after setting the path variables correctly.
I have uninstalled the Python 3.8.2 and after restart, the command
jupyter notebook
Worked perfectly :)
you can create a batch file and search for Jupiter in your windows search and ooen its properties and you will get this string.
D:\anaconda3\python.exe D:\anaconda3\cwp.py D:\anaconda3 D:\anaconda3\python.exe D:\anaconda3\Scripts\jupyter-notebook-script.py "%USERPROFILE%/"
after getting this you can create a jupitor.bat file with this content it that
and you can save that file in a script folder in d or any drive and add the path of your script file in your environmental path
and then you can easly call this by typing jupitor in cmd.
To install I used
"pip install notebook" in windows command line
To run python -m notebook did not work for me, but python3 -m notebook worked
First run this command
pip install jupyter
then add system variable path , this path is where jupyter and other scripts are located
PATH = C:\Users<userName>\AppData\Roaming\Python\Python38\Scripts
e.g PATH=C:\Users\HP\AppData\Roaming\Python\Python38\Scripts
After that we can run jupyter from any folder/directory
jupyter notebook
I just found that error when I first intalled and run the jupyter notebook. Then I found the executable (.exe) file from
C:\Users\<user-name>\AppData\Local\Programs\Python\Python39\Scripts.
The actual file name was "jupyter-notebook".
The installation guide says it as "jupyter notebook" to run the server. You have to run the command "jupyter-notebook" in the command line and it will be run. Thanks!
My problem was my user's folder had a space in folder name.
After creating a new user and switching to that windows user, windows shortcuts and links from within' Anaconda worked fine.
Windows 8.1 64 Bit. Latest Anaconda.
Note: I ended up uninstalling an reinstalling Anaconda but my sense is the problem was really just the space in the windows user username/user folder.
Using python 3.6.3. Here after installing Jupyter through command 'python -m pip install jupyter', 'jupyter notebook' command didn't work for me using windows command prompt.
But, finally 'python -m notebook' did work and made jupyter notebook to run on local.
http://localhost:8888/tree
Here is how I resolved stated issue, hope it helps:
install python 3.7 using official website for python, while installing include installing PATH by checking it's box
after that open cmd (be sure to open it after step 1) and write: pip install jupyter ENTER
now you should be able to open jupyter notebook by using command: jupyter notebook
Seems simple, but it may as well help.
In windows 10:
If you used anaconda3 for Jupyter notebook installation and forgot to check the box to add the environment variables to the system during installation, you need to add the following environment variables to the "Path" variable manually:
(search windows settings for Edit environment variables")
Environment variables for Anaconda3
If you have installed jupyter with
"python -m pip install jupyter" command
instead of
"$ pip install jupyter" command
then follow these steps:
Create a notepad
Change its extension from ".txt" to ".ipynb"
Right click it and click "open with"
In the pop up, go to - C:\Users\<"windows_user_name">\AppData\Roaming\Python\Python38\Scripts
Click on "jupyter-lab.exe"
100% working solution:
Follow these steps:
Open the folder where you downloaded "python-3.8.2-amd64.exe" setup or any other version of python package
Double click on "python-3.8.2-amd64.exe'
Click "Modify"
You will see "Optional features"
Click "next"
Select "Add python to environment variables"
Click "install"
Then u can run jupyter in any desired folder u desire
E.g open "cmd" command prompt
Type :
E:
E:\>jupyter notebook
It will get started without showing
'Jupyter' is not recognized
Thanks
I was facing the same issue in windows7, as i just recoverd my computer with the help of recovery point and after that notebook just stopped working. I tried to change the path setting but nothing was working so I just simply uninstalled the python with the application from which it was installed and after that I installed it again. After that I installed jupyter notebook again and then it worked fine.
Thanks
I just installed JupyterLab on top of my Python 3.8/pip enabled Win10 machine, so I ran into these startup problem with windows.
If everything is ok (check that you have PATH for Python, eg. C:\Users[Username]\AppData\Local\Programs\Python\Python38-32\Scripts) you simply run:
jupyter-lab.exe
and that's it.
Cheers
Add system variable path, this path is where jupyter and other scripts are located
PATH -->
`C:\Users\<userName>\AppData\Roaming\Python\Python39\Scripts`
Like in my laptop PATH is:
"C:\Users\developer\AppData\Roaming\Python\Python39\Scripts"
After that, You will be able to run jupyter from any folder & any directory by running the below command
jupyter notebook
Had the same issue. Finally searched where jupyter.exe directory was located on my computer. For some reason it was under
C:\VTRoot\HarddiskVolume4\Users[user]\AppData\Local\Programs\Python
Whereas the Python is
C:\Users[user]\AppData\Local\Programs\Python
So I copied full Python39 folder from VTRoot to main Python39 python folder in AppData. And the issue is solved.
First check where your python is installed by heading over to
C:\Users\**username**\AppData\Local\Programs\Python\Python39\Scripts
this is the path usually you will find python installed. After this type in
cd.. to get one step out of the Scripts folder
After this install jupyter in here using:
$ pip install jupyter
The installation was fine and when I tried to open the jupyter notebook, it gave me the following error.
'jupiter is not recognized as an internal or external command, operable program or batch file.
I checked a lot of resources but still, I faced the same problem. After doing a lot of stuff from the internet, I myself figured out that maybe due to some updates(for some users) it won't open by typing the command
jupyter notebook
Instead, you have to type
jupyter-notebook
The only thing I was missing was this Hyphen-minus. Hope this works for you too.
I've searched the web, and I'm still unclear on how to run R from the Mac terminal. I have Rstudio and the standalone R app installed. I thought I could just type "R" from the command line as I do with "python", but that doesn't work. Is it necessary to edit the PATH in my bash profile? If so, how do I give the correct location of R?
Thanks for any help
Edits after receiving comments
So, I'm running Sierra, and when I type "r" or "R" at the terminal, I get "-bash: R: command not found." If I type, "which R" in the terminal I do not get any output.
Here is the output from "echo $PATH": /usr/local/heroku/bin:/opt/local/bin:/opt/local/sbin:/Library/Frameworks/Python.framework/Versions/2.7/bin:/Users/samuelcolon/anaconda/bin:/Library/Frameworks/Python.framework/Versions/3.5/bin:/Users/samuelcolon/.rvm/gems/ruby-2.1.0/bin:/Users/samuelcolon/.rvm/gems/ruby-2.1.0#global/bin:/Users/samuelcolon/.rvm/rubies/ruby-2.1.0/bin:/Library/Frameworks/Python.framework/Versions/2.7/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/samuelcolon/.rvm/bin:/Users/samuelcolon/.rvm/bin
As for the installation, I believe I downloaded it directly from cran.r-project.org a while ago. I can locate the GUI in my applications and open it--
I have version 3.13. Is it possible, I only have R.app installed but not R? Perhaps that's the reason I'm getting the 'command not found' when typing "R" into the terminal?
Generally, I've been working in RStudio, but I'd still like to access R from the terminal and also to find where things are located. I'm fine with removing and re-installing R if it's easiest to start from square one. I hope the extra detail helps, and I appreciate the responses.
An answer for those not that familiar with Terminal and Bash.
I have done a fresh update install of R from the R.org cran site as part of seeking an answer to your question.
I found this latest install version 3.4.0 installs R for access in Terminal, and also installs R.app as part of the package.
To my understanding, reading support docs, if you have an older version of R it will update that. However it will not update an installation of R installed by the anaconda package.
Where are the R files stored?
I can only assume that with a fresh install of the latest R, R will work for you in Terminal.
To learn where the R files are that are being accessed - in Terminal after starting R, and in R.app, type:
>R.home()
In my case as example:
In R.app - the R version 3.4.0 is accessed in the top directory (not my user folder):
R.home()
[1] "/Library/Frameworks/R.framework/Resources"
In Terminal - the R version 3.3.2 is accessed in the Anaconda package, again in the top level directory.
R.home()
[1] "/anaconda/lib/R"
So I have two different versions of R, and Terminal accesses a different version to R.app.
How can I ensure I access the same version in Terminal as I do in the R.app?
For someone familiar with bash, and how the whole bash command system works I am sure there is a well constructed command. All the same here are some novice solutions.
-
• First Solution:
I could update the anaconda version, however, I would prefer not to as as other elements of the anaconda package my depend on this older version of R. For those not yet familiar with Terminal and bash, not such a novice solution.
-
• Second Solution:
This solution came from mko. It provides a single use solution. From the result above, and checking the directory structure a little further to find this R file.
Finding the significant R file enables me to edit an extension of the above path shown in the R.app. So add /bin/R to enter
/Library/Frameworks/R.framework/Resources/bin/R
Entering and pressing return will start R from this version.
Alternatively, one can find this file and icon in the GUI Finder, lead by the above result, and just double click on it, and it will open Terminal and a session with R running for you. Easy!
One could also make an alias of it and put it on your desktop for easy future starts.
-
• Third Solution:
My last solution I think may be best, adding to mko's solution. Make an alias.
Being in my home directory in Terminal I open .bash_profile using the nano text editor. (If you do not already know how to do this, then best not use this solution.)
I then add the line in this env file.
alias Rv340='/Library/Frameworks/R.framework/Resources/bin/R'
I then save the changes and exit this terminal session. I then open a new Terminal window. (This is so the changes to the env above are incorporated in the new terminal session).
Then when I enter the alias:
Rv340
The version of R I want opens.
You can choose a different alias name to "Rv340".
-
• Fourth Solution:
A second more permanent solution for opening the same version of R in Terminal is as follows.
Copy the path as showing in R.app in response to the R.home() command above, and add that path to PATH in your .bash_profile. (If you do not know already how to do this, then ignore this solution.) Do so as follows.
export PATH="/Library/Frameworks/R.framework/Resources:$PATH"
To my understanding, this ensures that bash looks here for R (and anything else), then moves on to the other paths in PATH. Since this adds this path to the beginning of $PATH, an env variable, bash looks here first where it finds the newer version first, and stops looking.
When it comes to understanding PATH in the env set up in .bash_profile the following two links were helpful.
About PATH.
How to correctly add a path to PATH.
This solution may muck with anaconda's invocation of R. I have yet to check this.
First of all, you have to start terminal application. You can use either built in Terminal.app, or you can use replacement. My favorite one is iTerm2
https://www.iterm2.com
Then, you simply open terminal window and run R. Just like shown below:
Have fun with R!
Just ran into the same issue when installing R-4.0.3.pkg on my MacBook (MacOS BigSur). Can open R.app to the clunky R GUI, but typing in 'R' in terminal doesn't work.
Turns out, an R executable lives here: /Library/Frameworks/R.framework/Versions/4.0/Resources/bin/R
So I added this alias to my newly created .zshrc script:
alias R '/Library/Frameworks/R.framework/Versions/4.0/Resources/bin/R'
Now when I type in R, it opens... I swear this all happened seamlessly in earlier versions.
There is currently a bug in CRAN's R installation package that results in it not correctly installing symbolic links to R and Rscript for commandline use. I've just verified this by inspecting the postflight script in their 4.0.5 installation package. This only impacts MacOS system releases of 20 and above (you can check with uname -r).
I've included more info here, along with what the "correct" fix should be: manually creating symbolic links to /usr/local/bin that point to the R and Rscript binaries themselves. If this is the current challenge, then this would be a far better solution to creating aliases or manipulating PATH in various ways, since it's what the installation package intended to do (and presumably will again soon).
R: command not found
In short, if this is the problem, then Ashkan Mirzaee's answer (https://stackoverflow.com/a/67202173/2093929) to create the symbolic links directly is correct in form, but might not have the right link command. The 4.0.5 package intends instead to use:
mkdir -p /usr/local/bin
cd /usr/local/bin
rm -f R Rscript
ln -s /Library/Frameworks/R.framework/Resources/bin/R .
ln -s /Library/Frameworks/R.framework/Resources/bin/Rscript .
You can create a symbolic link from R and Rscript binaries to /usr/local/bin to add them to the PATH:
sudo ln -s /Library/Frameworks/R.framework/Versions/Current/Resources/bin/R /usr/local/bin
sudo ln -s /Library/Frameworks/R.framework/Versions/Current/Resources/bin/Rscript /usr/local/bin
Now which R should return /usr/local/bin/R and you can use R.
An easy way to open RStudio with admin privilege on macOS:
Go to Applications, then right click on RStudio
Select "Show Package Contents"
Go to Contents/MacOS
Now open terminal(in bash mode). Type sudo and drag the RStudio.exec into terminal and press on ENTER
Now RStudio will have admin access!
I'm exploring package building on Windows 7 but have been running into trouble after reaching the Command Prompt stage. The following thread appears to be on the same topic that I'm having trouble with, but the question remains unresolved:
Cannot install R package in Windows 7
The problem: whenever I try an R CMD command in Command Prompt (e.g. I've tried R CMD install pkgName, R cmd install pkgName, Rcmd install pkgName, where pkgName is a place-holder for an actual package that has been R CMD checked on OS X and also posted on CRAN, where I have the unzipped source in the current working directory), I get the following error message:
'R' is not recognized as an internal or external command,
operable program or batch file.
(If I try the Rcmd install pkgName command, then the error starts out as 'Rcmd' is not ....) Note that even if I type in just R in Command Prompt and hit enter, I get the same error, so I'm not even able to bring up R here, though it opens perfectly fine in its stand-alone interface.
I have examined the following guides without success in identifying the trouble:
Karl W Broman's website
Rob J Hyndman's website
Steven Mosher's blog
The most immediate thing that came to mind was that the path variables in Windows were not set right, but this also has not (yet) led to the answer. For example, I have triple-checked the paths to ensure they are correct, including for the R version number, that x64 in the path name is accurate, etc.
I realize this is a complex issue to remotely diagnose, but any advice and suggestions on resolving this trouble is appreciated. For reference, below are the steps I have taken already to try to resolve this issue:
Uninstall R and Rtools
Install the latest version of R (2.15.0)
Install Rtools215 to match R version 2.15.0
Originally I let Rtools specify the path variables (turning that option on during installation). No success after this method.
I updated the path variables on my computer, where the below paths were used:
C:\Rtools\bin; C:\Program Files\R\R-2.15.0\bin\x64;
I've also tried the R CMD (and Rcmd) commands with the following paths included (note that these paths don't lead to anything on my computer, so I tried doing R CMD / Rcmd with and without them specified):
C:\Rtools\perl\bin; C:\Rtools\MinGW\bin;
Tried adding/removing the following path, which goes to the only other folder visible within the Rtools folder:
C:\Rtools\gcc-4.6.3;
Tried multiple variations of the R CMD commands, as noted earlier.
I tried this all a few months ago when I had R version 2.14.1 and Rtools214 installed, and I had the exact same trouble.
Note: I already had Cygwin installed prior to R and Rtools, and I have not installed MikTeX (yet).
Have you closed the command prompt and opened a new one after adjusting the PATH?
Enter the command PATH on the command line and ensure that you are properly updating your path
Try navigating to the directory where R.exe is saved and running it locally -- cd C:\Program...\bin\x64, R.exe.
Ensure that you're running on Windows' Command Prompt and not Cygwin's terminal
If you actually have a space after the semi-colon in your PATH, you'll need to remove that: /bin;C:/Program.... Try combining that with Joshua's solution.
I attach my whole solution here:
Install Rtools which is compatible with my R version
Add PATH: C:\Program Files\R\R-2.15.1\bin\x64;C:\Rtools\bin;C:\Rtools\gcc-4.6.3\bin
In cmd, enter: R CMD INSTALL packagename
Click "enter", done.
I had a lot of trouble getting this to work, and finally found the golden nugget on r-project (R doesn't like spaces in paths) so here's how I finally did all this:
I installed R to "c:\programs" instead of "c:\program files...". My final path to RSCRIPT.exe is "C:\Programs\R\R-2.15.2\bin\Rscript.exe"
I added that directory to my PATH, but that doesn't seem to help
RStudio is also installed under c:\Programs (e.g. c:\Programs\RStudio), but RTools is installed under the "c:\" root directory (e.g. c:\RTools).
I downloaded all the packages to "c:\downloads\r"
I opened a command prompt in "c:\downloads\r" and ran the R CMD install from this downloads directory, specifying the path to R
e.g. "C:\Programs\R\R-2.15.2\bin\x64\R CMD INSTALL colorspace_1.2-0.zip"
It appears that the CMD processor is Case Sensitive. You have to use INSTALL vs. install
Simple solution, use quotes:
c:> "C:\Program Files\WinZip\wzunzip.exe"
if you run this, you don't need to worry about the space in Program Files.
Hope this help.
I encountered a similar problem while trying to use SparkR from Windows Power Shell. Each time I would do ".\sparkR.cmd" (I was inside the folder containing this file), it would throw an error message like,
cmd is not recognized as an internal and external
command...blah...blah...blah.
I solved the problem by adding "C:\Windows\System32" to my PATH.
I restarted my system and then repeated the process and this time, I saw a new error,
R is not recognized as an internal and external
command...blah...blah...blah.
I tried all sorts of approaches, including the ones mentioned above. NOTHING WORKED, I was probably wasn't efficient enough to make it work.
Then I came across this place at code.google. I simply copied the R.bat onto a notepad, named it as R.bat. Kept it inside the folder where sparkR.cmd was located. For me it was,
C:\Apache\spark-1.5.1-bin-hadoop2.6\bin\
The I placed it on my PATH as :
C:\Apache\spark-1.5.1-bin-hadoop2.6\bin\R.bat
Restarted my laptop, opened my Power Shell as an administrator and typed :
.\R.bat help
It worked fine. Then I typed,
.\sparkR.cmd
and there it was.
It worked.
I hope it helps to people new to R. Thank you G. Grothendieck.
In the .bat file add a line of code specifying the path of the folder where R is installed and then give the path of the script as follows -
#ECHO OFF
PATH C:\Program Files\R\R-3.5.1\bin
R CMD BATCH D:\project_abc\helloworld.R
Following this, run the .bat file and you will see the code in the script will run smoothly.
In my case the issue was solved by using Edit instead of New while selecting PATH in the window below:
enter image description here
After selecting Edit I added the directory below:
C:\Program Files\R\R-4.0.2\bin\x64
This solved the issue in my case.
