python <3.10 fails on macos-14 with `dyld: Library not loaded`

[mbway]

Description:

When I run this pipeline:

name: MacOsTest

on:
  workflow_dispatch:

jobs:
  test:
    name: Test
    runs-on: macos-14
    steps:
      - uses: actions/setup-python@v5
        with:
          python-version: 3.9
          architecture: "x64"
      - name: print python version
        shell: bash
        run: python --version

It fails with:

Hello @mbway
Thank you for creating this issue. We will investigate it and get back to you as soon as we have some feedback.

[jmarrec]

macos-14 is an arm64 runner and you're explicitly requesting an "x64" architecture

[mbway]

Good point. I can't remember if it also fails without that. Either way the error message isn't very informative

Hello @mbway, Thank you once again for creating this issue.
We have reproduced the error in our local and found that the error is due to python <3.10 versions are not added to macos-14 runner image. Please find the screenshot for reference.

Please let us know in case of any further clarifications.

[mbway]

ok that makes sense. So I suppose my suggestion would be that the error message for a requested version being missing should be clearer

[aparnajyothi-y]

Hello @mbway, Thank you for the suggestion and we will look into it in future. For now we are closing this issue as setup-python is working as implemented.
