Tox is running different python version to the one installed by Github Actions

[elParaguayo]

Describe the bug
Tox is running different python version to the one installed by Github Actions.

When tox first upgraded to version 4, we pinned this to version 3 as tox-gh-actions didn't have support for version 4 at the time. Now that support is available I'm trying to upgrade our CI to use tox 4 but, when it runs, it's always running the py310 environment.

To Reproduce
Here is a run showing the issue. https://github.com/qtile/qtile/actions/runs/5719643898/job/15497980619?pr=4364 - this is run with tox -vv for additional debugging info.

While all tests pass, this hides the fact that they're all running py310. Take a look at the python 3.11 job - tox is called in "Run Tests" section.

Expected behavior
I expect the environment to match the installed python version as it did before updating to tox 4.

Additional context
Apologies if I've done something stupid here. Appreciate any help you can provide.

Hello, @elParaguayo.

I'm having a look at your PR: https://github.com/qtile/qtile/pull/4364/files#diff-ef2cef9f88b4fe09ca3082140e67f5ad34fb65fb6e228f119d3812261ae51449L20

I haven't verified by myself, but one hypothesis I have is that this change in the GitHub Actions configuration is causing the issue.

-               sudo pip -q install meson PyGObject
+               pip -q install "tox<4" tox-gh-actions 
+               sudo pip -q install meson PyGObject tox tox-gh-actions

I think sudo pip -q install meson PyGObject tox tox-gh-actions installs tox and tox-gh-actions to the system level's Python, not Python installed by actions/setup-python.

Could you try the following instead?

               sudo pip -q install meson PyGObject
               pip -q install tox tox-gh-actions
