Package Version

Run on macOS-13.2.1-x86_64-i386-64bit, but same problem also on linux.
Context
I stumbled in this error while building a python package for Arch: instead of using
check(){
cd "$_name-$pkgver"
PYTHONPATH=src pytest
}I tried
check(){
cd "$_name-$pkgver"
pytest -o pythonpath=src
}which fails with the above traceback.
I replicated the problem on a MacOs stripped down venv just to be sure that it is not related to the ArchLinux build env, which is quite complicated.
