In my Node.js functions, I have code that calls convert, which used to work but is now failing because it cannot find ImageMagick's convert command. What happened? Is there a way around this?
const args = [tempIn, "-thumbnail", "'258x258>'", tempOut];
spawnSync("convert", args, { encoding: "utf8", shell: true }); // error
// stderr: /bin/sh: 1: convert: not found
I'm aware that this command was changed to magick in ImageMagick version 7. It doesn't work with that command either. I'm also aware of supposedly current documentation that indicates the convert command is still installed.
ImageMagick and its command-line tool convert are included by default
within the Google Cloud Functions execution environment for most of
the runtimes. For PHP, you may need to do some manual configuration.
I also see there are questions on StackOverflow from 2019 mentioning npm packages such as GraphicsMagick for use with Firebase Functions. However, these packages presuppose the existence of the ImageMagick on the base system, which does not appear to be the case for me.
Lastly, I'm aware that there are and have been Firebase extensions for creating thumbnails, but for various reasons, I cannot use them.
If we consult this cloud functions system packages page, we see that ImageMagick was installed on the Ubuntu 18.04 images used for Cloud Functions. It also shows that ImageMagick is not present on the Ubuntu 22.04 images, which are presumably what it uses as I write this in 2023.
So the answer to what happend is that ImageMagick was deleted. In terms of what to do about it, unfortunately we are left to use the previous solutions for building and delivering our own binaries into cloud functions.

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:

The Julia Pkg documentation tells how to initiate an environment ($ activate $ENV-NAME), but it probably lacks the handy command to switch to the already created special environment. Also, I'm having trouble finding a command that shows all already created environments on the list, hence, if I have forgotten the names of the environments previously created, I need to do a manual search through the Julia-related folders...
So far, the verbatim help command in Julia REPL provides a poor description and so does the related Pkg-documentation webpage.
Another possible general answer to this predicament is to start using the Playground.jl module, which was recommended here on Medium:
However, the direct download attempt with Pkg repeatedly fails since the Pkg isn't able to find the package in the suggested GH project.
Thanks beforehand for any recommendations.
In package manager prompt just type activate # and press tab-key. The REPLs autocomplete will show you the possible environments.
If you are on a Mac or Linux
you can run this shell command to find all the "enviroment"
bash-3.2$ pwd

./symata/Project.toml
I am trying to follow this tutorial, in order to install the Nix package manager in my home directory instead of /nix.
I am doing the PRoot installation (see 2. in tutorial). At the end, the
tutorial proposes to be smart in Building native packages section, to be
able to run packages without PRoot:
To run packages natively (without PRoot) they have to be build from source because all paths to the nix store are hard-coded. It is simple, really:
mkdir $HOME/nix
nix-channel --update
env NIX_STORE_DIR=$HOME/nix nix-env -i nix
And now your Nix store gets built up using the new paths. The built binaries can be run directly from there.
I did that, but I don't see how it frees me from PRoot. If I don't do the /nix mounting point with PRoot, nothing works (no nix-env executable,
I can't install new packages).
Should this NIX_STORE_DIR environment variable be put in my .bashrc ?
It seems I always need to run PRoot because ~/.nix-profile points to
a /nix/... directory:
.nix-profile -> /nix/var/nix/profiles/default
There are more steps in the tutorial (5., 6.) - should I follow them ? It seems they apply only in case of using the manual installation (step 4.),
although it is not explicit.
Any help would be appreciated :)
For anyone stumbling on this old question: there is no currently supported way to install Nix without root. The above wiki was moved to https://nixos.wiki/wiki/Nix_Installation_Guide . It may well be out of date. PRoot could work, but even then, rebuilding the whole store at a different path is not a good idea, not the least because the binary caches won't help and you'll need to build everything.
I suggest trying Nix in a virtual machine or cloud server.
Future people from Google, it's still unsupported but does work. Script here that installs a couple dependencies, builds a temporary Nix, and uses that to install a proper version in your directory of choice.
I am trying to compile Network.HTTP (http://hackage.haskell.org/package/network) on win32/cygwin. However, it does fail with following message:
Setup.hs: Missing dependency on a foreign library:
* Missing (or bad) header file: HsNet.h
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
If the header file does exist, it may contain errors that are caught by the C
compiler at the preprocessing stage. In this case you can re-run configure
with the verbosity flag -v3 to see the error messages.
Unfortuntely it does not give more clues. The HsNet.h includes sys/uio.h which, actually should not be included, and should be configurered correctly.
Don't use cygwin, instead follow Johan Tibells way
Installing MSYS
Install the latest Haskell Platform. Use the default settings.
Download version 1.0.11 of MSYS. You'll need the following files:
MSYS-1.0.11.exe
msysDTK-1.0.1.exe
msysCORE-1.0.11-bin.tar.gz
The files are all hosted on haskell.org as they're quite hard to find in the official MinGW/MSYS repo.
Run MSYS-1.0.11.exe followed by msysDTK-1.0.1.exe. The former asks you if you want to run a normalization step. You can skip that.
Unpack msysCORE-1.0.11-bin.tar.gz into C:\msys\1.0. Note that you can't do that using an MSYS shell, because you can't overwrite the files in use, so make a copy of C:\msys\1.0, unpack it there, and then rename the copy back to C:\msys\1.0.
Add C:\Program Files\Haskell Platform\VERSION\mingw\bin to your PATH. This is neccesary if you ever want to build packages that use a configure script, like network, as configure scripts need access to a C compiler.
These steps are what Tibell uses to compile the Network package for win and I have used this myself successfully several times on most of the haskell platform releases.
It is possible to build network on win32/cygwin. And the above steps, though useful (by Jonke) may not be necessary.
While doing the configuration step, specify
runghc Setup.hs configure --configure-option="--build=mingw32"
So that the library is configured for mingw32, else you will get link or "undefined references" if you try to link or use network library.
This combined with #Yogesh Sajanikar's answer made it work for me (on win64/cygwin):
Make sure the gcc on your path is NOT the Mingw/Cygwin one, but the
C:\ghc\ghc-6.12.1\mingw\bin\gcc.exe
(Run
export PATH="/cygdrive/.../ghc-7.8.2/mingw/bin:$PATH"
before running cabal install network in the Cygwin shell)
I just updated R from version 2.15.1 to version 3.0.0 on my MAC running 10.6.8 and now R crashes on startup.
I get the error:
Error in getLoadedDLLs() : there is no .Internal function 'getLoadedDLLs'
Error in checkConflicts(value) :
".isMethodsDispatchOn" is not a BUILTIN function
Any ideas on how to go about?
The most common cause of this is having a corrupted ".Rdata" file in your working directory. Using the Mac Finder.app you will not by default be able to see files that begin with a ".", so-called dotfiles. Those files can be "seen" if you execute a change to the plist controlling the behavior of Finder.app. Open a Terminal.app window and run this bit of code:
defaults write com.apple.Finder AppleShowAllFiles YES
Then /point/-/click/-/hold/ on Dock-Finder-icon, and choose "Relaunch"
If you to do so, you can then change it back with the obvious modfication to that procedure. I happen to like seeing the hidden files so that's the way I run my Mac all the time, but some people may feel it is too dangerous to expose the "hidden secrets" to their own bumbling.
Paul raises a good point: I run the following R function in the R console after updating:
update.packages(checkBuilt=TRUE, ask=FALSE)
I have a lot of installed packages and paging through the entire list has gotten too tiresome so I bypass the ask-messages. Sometimes you will get errors because there may be dependencies on r-forge or Omegahat packages or on packages that need to be compiled from source. These may need to be updated "by hand". And you may need more than one pass through such an effort. Take notes of which packages are missing and fill them in.
I had the same problem running RKWard on ubuntu 12.04.
Check your r-base-core, like Paul suggested, to make sure the version is also at the latest version. Mine didn't update automatically. I had a platform dependent version, but RKWard was calling the new version. To solve this problem, I simply marked r-base-core for removal and reinstalled the latest version or r-base-core. poof problem fixed, bippity boppity boo!
I suspect that your error is similar to mine because I had also JUST updated RKWard. Start at updating r-base-core or try to get all of the dependencies to match up the versions.
I hope that you can translate this into what to do on a MAC,
SU
