So far, so good... but then it goes bad.

This apparently depends on a *different* version of pyqt5 which does not
have a compatible binary (compiled) wheel available, so the installer
process is going to try to build it for you. This rarely works on
Windows - you usually have to have some very precise setup - that is,
you have to be *planning* to build it, the convenience
build-because-didn't-find-wheel is very likely doomed to failure for
anything complex.
The pyqt5-tools package has not been updated for a year now, several
drops of pyqt5 have happened since, according to the history on
pypi.org. I'm assuming -tools are pnned to the same version of pyqt5,
but this is only a guess, could be some other mismatch.
Looks like there's an issue filed on this:
