PyQt5-5.8.2 doesn't function on Windows 10

Question

I need to install qscintilla. I use pip for that:

PyQt5 automatically upgrades to the latest ve

Answer 1

The root issue for me was different versions of PyQt wheel (5.9) and pyqt windows distro (5.6 - the last precompiled version available).

I found matching 5.6 wheel, but it only supported Python 3.5. So, I downgraded Python to 3.5 and installed PyQt5-5.6-cp35-none-win_amd64.whl

pip install pyqt5==5.6 

works equally well.
