unable to launch lutris on endeavouros (arch linux)

[albert-softie]

updated my system a few nights ago and any time i try to launch lutris it immediately crashes

Traceback (most recent call last):
  File "/usr/bin/lutris", line 58, in <module>
    from lutris.gui.application import Application  # pylint: disable=no-name-in-module
ModuleNotFoundError: No module named 'lutris'

It's not us, it's you (or Endeavor / Arch)

Some of the reasons this could happen:

• You have updated Python to a newer version and the Lutris package hasn't been updated to that version
• You have messed around with pyenv and Lutris is using the wrong python version

I want to find out the root cause of this so we can find ways to prevent it.
Right now, I'm considering a port of Lutris to Qt which would allow us to """""compile""""" the code into a single binary and not depend on the state of the user's Python installation. But if we go that route, this is going to take a very long time to achieve. There might be some workarounds we can find in the mean time.

I put some time into this issue today and ive solved it for me, i hope others with the issue can confirm the fix.

After comparing a fresh OS install on a vm to my non-working lutris install I noticed when i ranwhich python and which python3 the output on my non-working system was the wrong directory.

For me on Manjaro(Arch) the directory for each command should show /usr/bin, to set this correctly you just need to make sure there is no other versions of python overwriting it in local user folders such as /usr/local/bin or /home/user/.local/lib. Some programs like pyenv and conda change these directories automatically.

You should also make sure the lutris module is actually in the right python folder /usr/lib/python3.11/site-packages/lutris
