Problem with new install of wxPython

I successfully installed wxPython (latest version) but get the following exception at line 12 of

from ._core import *
Exception has occurred: ModuleNotFoundError (note: full exception trace is shown but execution is paused at: _run_module_as_main)

I have uninstalled and reinstalled a couple of times with the same result. Installation for me was more than simply pip install wxPython. I have to first install “attrdict3” and “requests” and, of course, Visual Studio Community Edition (I’m on Windows 11). As I say, with these caveats, installation is a success:

(venv) C:\Users\dcox1\Development\wxpython>pip install wxPython

DEPRECATION: wxPython is being installed using the legacy ‘ 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

pip list gives the following:

Package Version

certifi 2022.12.7
charset-normalizer 3.1.0
idna 3.4

pip 23.0.1

Update: I was able to get around this problem by uninstalling wxPython and reinstalling with the following command:

pip install -U --pre -f wxPython

Thanks to Robin Dunn for this suggestion
