I'm trying to install PyQt on a windows computer without internet connection. The computer seems to have a very recent version of Python (Python 3.9.2) so the older.exe files available online don't seem to be compatible.
I downloaded the whl file (PyQt5-5.15.4-cp36.cp37.cp38.cp39-none-win32.whl) but I'm not entirely sure where to put it despites trying to print(sys.path) as recommended here.
Update: I managed to unzip the whl file and tried placing it in several locations, amongst them the site-packages folder but it still doesn't seem to be working.
Any idea how to get this working?
