google-cloud-sdk needs python2 to work

mmoya opened this issue · comments

commented

gcloud needs python2 to work. The dependency shouldn't be optional.

Steps to reproduce:

$ yay -Q google-cloud-sdk
google-cloud-sdk 354.0.0-1
$ yay -Rs python2
$ python2
bash: python2: command not found
$ gcloud
/opt/google-cloud-sdk/bin/gcloud: line 194: /usr/bin/python2: No such file or directory
commented

This is not the case for a default installation.

➜ pacman -Qi python2
error: package 'python2' was not found

➜ gcloud --version
Google Cloud SDK 354.0.0
alpha 2021.08.20
beta 2021.08.20
bq 2.0.71
core 2021.08.20
gsutil 4.67


➜ gcloud
ERROR: (gcloud) Command name argument expected.

Can you please include the output of `the following commands?

$ stat $(command -v python)

$ gcloud --verbosity=debug info

And additionally, for good measure:

$ cat /etc/profile.d/google-cloud-sdk.sh
commented 
$ stat $(command -v python)

Do you have something installed at /usr/bin/python2? Run stat /usr/bin/python /usr/bin/python2.

commented

^ That will help further debug your issue, but I should note, this is explicitly your issue. You are using pyenv, which is proxying ~/.pyenv/shims/python out to /usr/share/pyenv/libexec/pyenv-exec, which is responsible for detecting the version of python you've configured your shell environment to use and exec-ing out to it.

/opt/google-cloud-sdk/bin/gcloud is a shim that simply uses exec to hand off to the specified python version, which in this case is pointing to ~/mmoya/.pyenv/shims/python.

commented

I installed pyenv to try to recreate your issue. Here's what happening under the hood.

  • gcloud execs into CLOUDSDK_PYTHON, which is set to python
  • python is really ~/.pyenv/shims/python
  • ~/.pyenv/shims/python execs into /usr/share/pyenv/libexec/pyenv-exec with the arguments "python" and "<args...>", which ends up being something like exec /usr/share/pyenv/libexec/pyenv-exec python "$CLOUDSDK_PYTHON_ARGS" "/opt/google-cloud-sdk/lib/gcloud.py" "<gcloud args...>"
  • /usr/share/pyenv/libexec/pyenv-exec calls /usr/share/pyenv/libexec/pyenv-which to determine the path to the python installation specified on the command line before handing off
  • /usr/share/pyenv/libexec/pyenv-which reports back /usr/bin/python2
  • /usr/share/pyenv/libexec/pyenv-exec completes the chain by handing off to /usr/bin/python2, which apparently doesn't exist.

I was not able to get pyenv-which to report back /usr/bin/python2 for the argument python unless I manually created a /usr/bin/python2 executable file and manually wrote /usr/bin/python2 into ~/.pyenv/version. I'm going to close this out, because it is not a package or upstream issue, but would be interested in what you find out is causing your problem.

I'd recommend taking a look at your local ~/.pyenv/version file, pyenv global, pyenv versions, pyenv which python, and /usr/bin/python2 to further debug this.
