Install QT action fails with "error: invalid command 'bdist_wheel'"

[bznein]

Our workflow is here: https://github.com/BitBoxSwiss/bitbox-wallet-app/blob/master/.github/workflows/ci.yml#L227-L234

and it started failing this morning with the error
" error: invalid command 'bdist_wheel'"
(https://github.com/BitBoxSwiss/bitbox-wallet-app/actions/runs/14240223810/job/39910366635)

A workaround seems to be to manually install wheel as shown in BitBoxSwiss/bitbox-wallet-app#3282

Seems related to pypa/wheel#660

Also seeing this: https://github.com/danmar/cppcheck/actions/runs/14344212879/job/40210506168. Strangely it was still working like an hour ago.

This is really breaking things - and not helping Qt based projects trying to migrate out of the Linux Ubuntu 20.04 based runner which will be dropped from GH actions next week. Is there any workarounds?

[SlySven]

Humm, I am NOT a python user but it seems that the Python wheel package version 46.x is broken but it is included by default somehow. I thought I might be able to fix that by downgrading before uses-ing jurple/install-qt-action in my GH action .yml file:

    - name: Manually install old version of the python wheel package
      run: |
        pip install 'wheel<0.46.0' --force-reinstall -v
        # We need to install older wheel otherwise the below will fail
        # with "invalid command 'bdist_wheel'"
        # See https://github.com/jurplel/install-qt-action/issues/281
      shell: bash

    - name: Install Qt
      uses: jurplel/install-qt-action@v4
      with:
        version: ${{matrix.qt}}
        dir: ${{runner.workspace}}
        modules: 'qt5compat qtmultimedia'

However that doesn't work because the setup of this action reinstalls the later version. See the third and fourth step in this log:
https://github.com/Mudlet/Mudlet/actions/runs/14346515238/job/40217269201?pr=7806

Is it possible to downgrade the version of wheel used - is it something configured within this action or is it now part of the whole GH runner environment? If it is the latter than this is really going to mess up a lot of Qt projects on GH!

[jdpurcell]

I submitted PR #282 and it's also fixed in my fork; feel free to use jdpurcell/install-qt-action@v5 instead of jurplel/install-qt-action@v4 until the PR gets officially merged/released.

@SlySven I suspect the delay comes from the cache mechanism, I failed yesterday for me and I see that my previous workflows uses the cache, the failing one trigger a full install. Thanks @jdpurcell for the fix.

[firewave]

It indeed is triggered when the cache fails (from my previously posted failure):

Warning: Failed to restore: Cache service responded with 422
Automatic cache miss, will cache this run

Since the cache is working again the issue "disappared".

[jdpurcell]

There was a brownout of the cache service yesterday before it goes offline next week (see #280). That coming back online helped, and the wheel 0.46.1 release was taken down too (see pypa/wheel#662). So install-qt-action should be working fine now, but I'll leave up the PR as it sounds like correct long term solution is to rely on a newer setuptools that doesn't need wheel.
