Can't run the demos and samples

Hey there, new here. I have wxPython 4.3.2 installed but when I attempt to run demo.py, it tells me that it was built for 4.2.5 and then I get an error that the Mac Speller isn’t found. So I uninstalled 4.3.2 and tried to install 4.2.5. This results in “failed-wheel-build-for-install”

× Failed to build installable wheels for some pyproject.toml based projects
╰─> wxpython

Not sure what to do from here. Are the demos and samples supposed to run on 4.3.2?
