`setup-python` failing for 3.8 on `macos-latest` about setup-python

[aparnajyothi-y]

Hello @abravalheri, Thank you for creating this issue and we will look into it :)

I don't think I am.

Sorry, I didn't mean "you"... I meant the code within the action.

I'm also experiencing the same issue as you, but wanted to share some information based other issues I've noticed with the new arm64 runners. I don't think github vetted the change to macos-14 (arm64) very well before making it the latest. Ideally all the actions they maintain should have been compatible with new architecture out of the box.

Update: even if I invert the order between checkout and setup-python so that setup-python is the very first action to run, it still fails: pypa/setuptools#4343.

macos-latest was recently changed from macos-13 to macos-14. macos-13 was x86_64, while macos-14 is arm64.

This action fails on macos-latest from python 3.8, 3.9, and 3.10... but seems to be okay with python 3.11.

If you're relying on packages installed by homebrew or pre-installed to the runners, then the homebrew path is different on arm64 macs, verus the x86_64. The new path is /opt/homebrew instead of /usr/local.

Hi @ReenigneArcher, thank you very much for having a look on this.

Yeah, I need this specifically on Python 3.8 (I did notice it work fine on 3.11).

If you're relying on packages installed by homebrew or pre-installed to the runners, then the homebrew path is different on arm64 macs, verus the x86_64. The new path is /opt/homebrew instead of /usr/local.

I don't think I am. Even when actions/setup-python@v5 is the very first step to be executed in the job, with no custom code before, it fails. I never get past actions/setup-python@v5 to have the chance to use pre-installed packages or packages installed by homebrew...

You can see more details and the workflow file in pypa/setuptools#4343.
