You can't. With compiled binaries, especially, it's important to install into each version separately - there can be minor differences which will be taken care of by the installer. Normally, that's not a problem, other than that you have to install each one again; the best way would be to keep track of your package dependencies in a file called requirements.txt, and then you can simply install from that (python3 -m pip install -r requirements.txt) into the new version. As to PyQt5 specifically, though.... I don't know what the issue here is, but I tried it on my system and it successfully installed version 5.15.4. Are you using the latest version of pip? There might be some other requirements. Alternatively, I'm seeing a potential red flag from this line: > C:\Qt\4.7.4\bin\qmake.exe -query You're trying to install Qt5, but maybe it's coming across a Qt4 installation? Not sure if that's significant or not. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
