What works

installing other packages works, e.g.

py -3.10-64 -m pip install -U mido
Requirement already satisfied: mido in c:\python311\lib\site-packages (1.2.10)

Version info

Windows 10 22H2
pip 23.0.1 from C:\Python311\Lib\site-packages\pip (python 3.11)

Context

This is used in the fluidpatcher installer, I logged a bug here.

Update 1

Seems to be a known issue reported here: https://github.com/wxWidgets/Phoenix/issues/2296

Tried workaround of manually installing

py -3.10-64 -m pip install -U attrdict3

Which installs.

Then retried the wxpython install

py -3.10-64 -m pip install -U wxpython

Which fails, this time with a different error message

Installing collected packages: wxpython
  DEPRECATION: wxpython is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

Update 2

Workaround: install Python 3.10.

For those who are still interested: I have successfully installed wxPython on Windows, under WinPython 3.11.1 (got it from SouceForge) with:

pip install -U attrdict3
pip install wxpython

After installation, in the \Lib\site-packages\wx dir, you have to rename all files with no extension manually so they have the .pyd extension.
