Why do the PySide6 Qt modules cause Tox to fail during a GitHub Action?

I have a python project that I am trying to test with Tox in GitHub Actions. Unfortunately the package PySide6 and its Qt modules causes Tox to fail when I have any python file that has any kind of import such as the following:

from PySide6.QtWidgets import QApplication

The issue seems to be the fact that PySide6's Qt modules cannot be located/opened/or something else during the github action run. If I change the import to simply import PySide6 (or only use any other package like pandas for example) and run my tox github action again, everything passes successfully.

I looked at PySide6's __init__.py and noticed that it seems to load its Qt modules in a non-traditional way and was wondering if that had something to do with it.

Regardless, here is the error message I get from tox in github actions when I have something like from PySide6.QtWidgets import QApplication in my code...

I can see that PySide6 and it's Qt modules do get installed by pip successfully before this test is run so I can't figure out why I'm getting the error. I even forcefully install the modules before the test to make sure they are in the environment:

      - name: Manually install PySide6 modules
        run: |
          python -m pip uninstall pyside6 shiboken6 PySide6-Essentials PySide6-Addons
          python -m pip cache purge
          python -m pip install pyside6 shiboken6 PySide6-Essentials PySide6-Addons

I was initially led to this solution but I don't know if it applies to my situation and I'm not using docker and don't know how to convert this to a solution for me anyways.

(And by the way of course, running the tox command locally produces no errors in any situation.)

How do I resolve my error with the PySide6 package causing this issue with Tox in GitHub Actions?

Not entirely sure if this relates, but I had a similar issue with "libEGL.so.1 not found" when running unittests in a Github Action for a repo that used PySide6. My issue came from PySide6.QtUiTools import loadUiType, and it seems this depended on the libEGL.so.1.

I added an additional step in my Workflow File:

  - name: Install dependencies
    run: |
      sudo apt update && sudo apt install -y libegl1-mesa-dev

And that seemed to solve the issue. Hopefully that might help you out as well?
