Running RasPi OS on a Pi 4b, 8 gig RAM, 256 gig UHS-1 u-SD card, pip and setuptools upgraded, python 3.7.3.
Warning for Pi users - There is a possible precedence issue during python upgrades, I have needed to use sudo to make sure the distro packages are upgraded. Not using sudo has packages installed under the user's .local/bin - and the /usr libs have precedence.
On to the error:

Going to previous revision does not fix issue. Other packages (such as numpy) have installed or upgraded just fine. PyQt5 install under Windows 10 worked fine.
Has anybody got a fix for this?
