Expected Behavior

pytest should not fail

To Reproduce

I'm packaging your module as an rpm package so I'm using the typical PEP517 based build, install and test cycle used on building packages from non-root account.

• python3 -sBm build -w --no-isolation
• because I'm calling build with --no-isolation I'm using during all processes only locally installed modules
• install .whl file in </install/prefix> using installer module
• run pytest with $PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>
• build is performed in env which is cut off from access to the public network (pytest is executed with -m "not network")

As long as in pyprojecct.toml is requires-python = ">=3.10" and this unit has name suggests that is is related to python 3.8 I think it is possibility that this unit can be removed.
