Where did this one come from? The "cp37" seems to imply it is a Python
3.7 variant.

You also didn't include the command line that started this sequence...

>(venv) PS C:\Users\gorev\OneDrive\Desktop\Medidost> ^C

... was it also run from inside the virtual environment?

>(venv) PS C:\Users\gorev\OneDrive\Desktop\Medidost> pip install pyqt5-tools 

Personally, anytime I see OneDrive involved, my first thought is to
blame it (It plays hob with multi-file relational databases, such as Visual
FoxPro used by the TMG genealogy program -- VFP opens/closes table files
(there are three per table) on an as-needed scheme; OneDrive sees a
modified file and locks it while synching it to the cloud -- and that
blocks VFP from being able to do the next update, and often causing
corruption of the database when the three table files become
unsynchronized).

However... as a test (note: I have Python (an older ActiveState build)
installed "for all users", and not in a user specific install.

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:
