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?

[hugovk]

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. :)

i still get this error with python 3.11.2. any idea how to fix it? i'm using python 3.11.2 and pytest 7.2.1

Open a new issue with a minimal reproducible example if you're having a problem. Commenting "this still happens" with no additional details on a two year old closed issue isn't helpful.

Do you have an old version of the package py installed inadvertently? (pip show py)

If so then:

• if you definitely still need py then upgrade it to 1.11.0
• it might be that you no longer need py at all:
  • for me it was left over from having been required by older version of pytest
  • pytest 7.2.0 removed py as a dependency "but will use the py library if it is installed" ⚠
  • so if you don't need it for anything else, simply remove it from your env: pip uninstall py & pytest will start working
