cp38-macosx_arm64 produces a x86_64 wheel

[ns-yanghsing]

Description

I'm building a library wrapping c++ code on macos with Github Action.
In the cp38-macosx_arm64 (os: macos-14) build, the "Building wheel" step went through, but the "Repairing wheel" step failed with

  delocate.libsana.DelocationError: Failed to find any binary with the required architecture: 'x86_64'

The issue only occurs on cp38 where cp39-macosx_arm64 went through without problems.

Here's the log for "building wheel", which passed but seemed to produce a x86_64 wheel for an arm64 build:

+ python -m pip wheel /Users/runner/work/py_jwt_cpp/py_jwt_cpp --wheel-dir=/private/var/folders/g6/rgtlsw6n123b0gt5483s5_cm0000gn/T/cibw-run-b894xoq9/cp38-macosx_arm64/built_wheel --no-deps

@ns-yanghsing Did you ever solve the issue or find a workaround? I think I'm seeing a related error in #2111.

[Czaki]

@patrikhuber you need to setup python 3.8 using github actions setup-python action to setup python 3.8 on macos arm runner.

Official installer for python 3.8 don not support macos arm runner.

[long2ice]

So any solutions?

[Czaki]

@long2ice follow the documentation https://cibuildwheel.pypa.io/en/stable/faq/#macos-building-cpython-38-wheels-on-arm64 and install python 3.8 using actions/setup-python@v5
