This is already fixed in pylib, we need to re vendor apipkg and give it a release

[henryiii]

This is affecting pybind/pybind11#3368 and pypa/build#376, so would be much appreciated :). Would you like me to make a PR to add it to your test matrix?

A new release of py is needed: pytest-dev/py#273.

In the meantime, you could try installing py directly from GitHub?

[henryiii]

Latest git py works! Thanks, that’s an acceptable solution for an alpha release of Python. :)
