   What library are you installing? This looks like a bug in the library, not CPython itself.

   And which version of Python? “ CPython versions tested on: 0.29.28” isn’t right.

   @ericvsmith A path from the error message suggests it's 3.10.

   @AlexLuya Can you write here an output of python --version? It gives a full version.

   This looks like a recent Cython version to me. Post it on the Cython bug tracker instead. https://github.com/cython/cython/issues

   Remember to include enough code to actually reproduce the bug.

   (Or of course it may be an issue in whatever package you're trying to install. In which case you should report it to them and not Cython)

   My conclusion having looked at it as a Cython issue: I don't think this is a Cython issue (even though a Cython version was quoted I don't think it looks like Cython-generated code).

   Whatever library it was was probably broken by #19975. It looks from the description there that this change was expected and intended to break some C API code.

   And you probably just want to replace PyList_SET__ITEM with PyList_SetItem. Maybe.

    Closing since this doesn't seem to be a bug in CPython (and likely not in Cython either, thanks @da-woods for looking).
