“Can Debian install wxPython and attrdict modules to fix ModuleNotFound error?”

System Details:

• Machine: Raspberry Pi Model 4B – 4GB
• Operating System: Debian 11 (Bullseye)
• wxPython version: 4.2.0 from pypi
• Python version: 3.11.3 built from source

Problem Description:

When installing wxPython (latest version 4.2.0) I am getting an error that the attrdict dependency is not found, even though it is installed.

(.venv) user@raspberrypi:~/Documents $ python --version
Python 3.11.3

(.venv) user@raspberrypi:~/Documents $ python -m pip freeze
attrdict==2.0.1
attrdict3==2.0.2
dbus-fast==1.86.0
pytz==2023.3
six==1.16.0
tzdata==2023.3

(.venv) user@raspberrypi:~/Documents $ python -m pip install wxPython

Why is it saying that the dependency cannot be found when it is clearly there? Is there any way to correct this error and install wxPython on my system?

I have also opened an issue in the wxPython GitHub page: https://github.com/wxWidgets/Phoenix/issues/2401
