pip on macos-12 does not support wheels built on the same platform (problem appeared on Jul 21)

[slayoo]

Description:
(seems similar to #279)
wheels built locally are not installable, pip debug does not list host platform as one of compatible tags

Action version:
worked OK up till today with sys.version: 3.10.5 (main, Jun 7 2022, 06:48:49) [Clang 12.0.0 (clang-1200.0.32.29)]
fails since today with: sys.version: 3.10.5 (main, Jul 11 2022, 14:33:08) [Clang 12.0.0 (clang-1200.0.32.29)]

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:

Run actions/setup-python@v1
  with:
    python-version: 3.10
    architecture: x64

  macOS
  12.4

Repro steps:
pip debug --verbose

this morning (when it worked OK, https://github.com/open-atmos/PyPartMC/runs/7449996034?check_suite_focus=true):

...
Compatible tags: 2083
  cp310-cp310-macosx_12_0_x86_64
  cp310-cp310-macosx_12_0_intel
  cp310-cp310-macosx_12_0_fat64
  cp310-cp310-macosx_12_0_fat32
...

a few hours later (https://github.com/open-atmos/PyPartMC/runs/7454643791?check_suite_focus=true):

...
Compatible tags: 1807
  cp310-cp310-macosx_10_16_x86_64
  cp310-cp310-macosx_10_16_intel
  cp310-cp310-macosx_10_16_fat64
  cp310-cp310-macosx_10_16_fat32
  cp310-cp310-macosx_10_16_universal2
...

Expected behavior:
A python package wheel built on a local machine should be installable on a local machine.

Actual behavior:
It is not, pip claims that ...macosx_12_0_x86_64.whl is not a supported wheel on this platform.

Hi, @slayoo 👋 Thank you for the issue, as a workaround you can try to specify the env.variable SYSTEM_VERSION_COMPAT: 0 on the job's level, as it was suggested here:

build:
    needs: [todos_annotated]
    strategy:
      matrix:
        platform: [ubuntu-latest, macos-12, windows-latest]
        python-version: ["3.7", "3.8", "3.9", "3.10"]
        exclude:
          - platform: macos-12
            python-version: "3.7"
          - platform: macos-12
            python-version: "3.8"
          - platform: macos-12
            python-version: "3.9"
    runs-on: ${{ matrix.platform }}
    env:
      SYSTEM_VERSION_COMPAT: 0
    steps:
      - if: startsWith(matrix.platform, 'macos-')

Please, let us know if this workaround is working for you 💌

Thank you, I will try it as a workaround and report back.
Still, it would be great to be able to:

• not need to communicate such workarounds to everyone downstream who wants to use the package on Github Actions
• test if package installation works on a given macOS release (which is the very reason why we are calling pip install before uploading to PyPI.org in these workflows)
• avoid such surprising random-looking regressions as the one that happened with the Jul 11 builds

Thanks for your help

(just confirming, the env-var workaround seems to work with 3.10.5 (main, Jul 11 2022, 14:33:08))

Thank you for your feedback, @slayoo 💌

By now I'm going to close this issue, If you have any questions feel free to ping us.

I don't really get why this is considered resolved. Only a workaround was provided, not a fix.
