I'm trying to execute code on R with the package RSelenium to do some webscraping, but I'm blocked at the very first step. After loading the library, I try to run this line of code:
rmDr <- rsDriver(browser = "chrome", chromever = 'latest')
But the console returns :
Error in java_check() :
PATH to JAVA not found. Please check JAVA is installed.
Java is indeed installed on my computer, but I'm guessing the path isn't the one the package is waiting for. Does someone know where I could modify the path in the RSelenium package code so that I can run this?
To be noted, I'm working on a company computer and so I don't have every admin rights.
Thanks for your help!
You can use method "remoteDriver()" instead of "rsDriver()". I checked it today with the last stable version of selenium driver (3.141.59) and it works perfectly.
Here's the code sample:
library(RSelenium)
driver <- remoteDriver()
driver$open()
driver$navigate("https://www.google.com/")
Just got the same error, installed the latest Java Development Kit (JDK), restarted a machine and everything worked ok.
The best way to use RSelenium is to go through Docker.
I used this tutorial, https://rpubs.com/johndharrison/RSelenium-Docker, not a long time ago, all went smooth.
Besides, you need a debugger, you can not scrape without it. That's why this tutorial is a good idea.
Let know if anything goes wrong.

I've checked the other questions and this case doesn't seem to be covered. I'm running Ubuntu in WSL on my windows machine and I'm trying to run GNATStudio, any time I attempt to run the program either via Alire or by calling it I receive the following error.
error while loading shared libraries: libxcb-shm.so.0: cannot open shared object file: No such file or directory
I've already done the basics, and verified I have the correct file installed. Calling apt-file find produces the following.
root#DESKTOP-F319G5G:/opt# apt-file find libxcb-shm.so.0
libxcb-shm0: /usr/lib/x86_64-linux-gnu/libxcb-shm.so.0
libxcb-shm0: /usr/lib/x86_64-linux-gnu/libxcb-shm.so.0.0.0
I've confirmed the location is in my path, as well and have restarted a few times. I'm really not too sure what my next steps should be. Any help is much appreciated!
The comment by #Bib solves this question: "install the libxcb-shm0-dev package."
I've searched for tutorials to help configure the package in my PC, and I've found this one: https://www.youtube.com/watch?v=_fDhRL_LBdQ
I executed every part of the code interactively with the tutorial, but when I run ee_install() (after installing miniconda with py_discover_config() and other packages previously, such as reticulate), but it keeps me returning an error saying that anaconda is mandatory for the package since I'm a windows user.
Here is the error I get:
Error in ee_install_set_pyenv_env(py_env = py_env, py_path = python_path, : Windows users must install miniconda/anaconda to use rgee. The use of a Python environment is mandatory.
I've just installed Anaconda (full version with navigator) and I set a new python environment called "py2r" and tried to use the function ee_install_set_pyenv(), passing the path to the environment created through Anaconda Navigator (which has a python.exe) as paremeter to py_path and the name "py2r" as paremeter for py_env arg. And yet, it didn't work.
What am I missing?
In case you want to take a look at the code, I can provide it, but I don't think it's necessary because is a simple test script that follows as I described.
Thanks for your attention and congratulations for the library, it will be very usefull for me at work!
I fixed the ee_install() problems bypassing them and doing every passage manually. It will require no more then 10 mins and you will probably fix the installation problems. You can find and follow the manual installation with this tutorial:

I installed Scilab 5.5.2 on Windows 10, and then installed the Scilab Code Generator toolbox.
However, when I start Scilab, the following message appears and I can't use the toolbox. This problem occurs for every toolbox.
Start Scilab Code Generator
Version: 0.9.20190122
Load macros
atomsLoad: An error occurred while loading 'xcos_code_generator-0.9.20190122':
File "C:\Users\光\AppData\Roaming\Scilab\SCILAB~1.2\atoms\x64\XCOS_C~1\09E129~1.201\macros\names" does not exist or read access denied.
(光 is my username.)
I suppose the problem comes from "\Scilab\SCILAB~1.2" in the middle of the file path. In my computer, the only folder in "Scilab" is "scilab-5.5.2", so indeed the software cannot find the file it's looking for.
Does anyone have any ideas?
I need to use the toolbox at work soon, so any help is greatly appreciated. Thank you in advance.
Note: I'm not using the latest Scilab 6.0.2 because it fails to work on my computer. It closes immediately after I open it.
I solved the problem by myself.
It was my user name "光" that caused the problem. I found people saying that user names in full-width characters such as Japanese sometimes cause problems like this.
The solution is to create another user account with a name in half-width characters and install Scilab in that account. (Just changing the full-width user name doesn't work because it doesn't change the filenames that already exist.)
I couldn't find the solution until today because I was searching for solutions only in the context of Scilab, not in the context of software in general.
I hope this answer helps someone.
I'm not sure why you are using an outdated version of Scilab. The latest version is 6.0.2 on Windows. If the newer version doesn't work properly then that's the problem you need to fix first. To test your Scilab installation you may run it in the terminal. Find the installation folder. For me, it is C:\Program Files\scilab-6.0.2\bin the on cmd go to the path and run Scilex.exe. If not uninstall everything and install it in a proper way. My recommendation is to uninstall the old Scilab you already have. Then:
Install Chocolatey package manager
Open PowerShell as Admin and run choco update all -y, once in a while update your packages this way.
run choco install Scilab -y
then open the Scilab software
run the atomsInstall("xcos_code_generator") in the console
runt the atomsLoad("xcos_code_generator") to make sure your package is installed properly. You should see this as a result:
--> atomsInstall("xcos_code_generator")

I have a file right here: Library ../../MyLib/My_Lib.py, and I try to import the python file in RIDE, but RIDE still report "FAIL : No keyword with name '****' found", and this keyword is defined in the My_Lib.py, seems RIDE cannot find the python file.
I using python 2.7.8+Robot Framework 3.1.2+windows server 2012r2. I even selected Library -> Name -> Browse in RIDE, but the error still there and this whole robot test case folder is copied from another server which is working fine
Can anyone suggest what have I missed?
Ah! I have worked this out, if anyone else meets the same issue, you can click Tools->view RIDE Log, to see what's happening there. For my case, it's because I didn't install thrift but the My_Lib.py obviously used thrift module, so the My_Lib.py compile failed with "No module named thrift.Thrift".
Is it possible the Python library was created to work with Python 3.x.x leading it to not work on your Python 2.7.8? See https://wiki.python.org/moin/Python2orPython3
Check what python version is being run on the other server where the test is running fine. You might need to update your local Python version.
Also, you could try running the Robot test outside of RIDE just in case. You may do so by navigating to the test folder where the .robot file resides and running the following command:
robot test_file_name.robot
See if you get the same error that way. Please report back after doing the mentioned checks and we can continue debugging, my reputation doesn't let me comment on your question so I will just update the answer as we go along.
I'm trying download scripts onto my atom editor. but I'm getting a strange error that I believe has something to do with node? This is one of the first packages I've tried to install so any help would be great. Here is the error.
You seem to have some connection problem to github. You should try to clone that repositry directly with git. Most likely ssh-connections don't work from your location..
