Future of `wheel.macosx_libfile`

setuptools version

setuptools==78.1.0

Python version

Python 3.10

OS

macOS

Additional environment information

No response

Description

Getting the error below when trying uv sync. Seems to be happening due to this import.

As I see from the latest wheel release that the file, src/wheel/macosx_libfile.py, is no longer present. It was present in the previous wheel release

Error stack trace:

          from wheel.macosx_libfile import calculate_macosx_platform_tag
      ModuleNotFoundError: No module named 'wheel.macosx_libfile'

Expected behavior

The imports should work for the latest setuptools release

How to Reproduce

Try to create a virtual environment with the latest setuptools==78.1.0.

Start with setuptools/command/bdist_wheel.py, especially get_platform and its import of wheel.macosx_libfile, and compare that dependency with the current wheel release. Reproduce the failure using setuptools==78.1.0 on Python 3.10 with uv sync. Done means the latest setuptools and wheel versions build successfully without the ModuleNotFoundError.
