Here is how I configured my installation to let me either use or not use pyqt6. Obviously it's a Windows computer:
1. Create new directory. I used %USERPROFILE%\.python\site-packages 2. Cut all the installed pyqt6 directories from the standard Lib\site-packages directory. 3. Paste the pyqy6 directories into the new .python\site-packages directory. To run without pyqt6, I just launch Leo as usual. To run using pyqt6, I set the PYTHONPATH environmental variable: set PYTHONPATH=%USERPROFILE%\.python\site-packages Now Leo will launch using pyqt6. If you have copied all the pyqt6 install directories also, then pip will find them and be able to properly list pyqt6 as well as the pyqt5 that is in the standard location.
