tests: make test-install.t work on debian systems

Authored by spectral on Jul 24 2020, 6:25 PM.



Debian systems, at least as of their version of python3.8 on my machine, have
rewritten some logic in ensurepip to make it not use the wheels in pip._bundled,
but instead to use wheels installed in /usr/share/python-wheels. It copies these
wheels into the virtual environment when it's created, and installenv/bin/pip is
able to see them and use them, so it thinks that 'wheel' is installed, and that
it can build the mercurial wheel instead of just installing it. For some reason,
when it subprocesses to run python3 bdist_wheel, it does
*not* have the 'wheel' wheel available, and we get an error message.

Debian's perturbations to how Python is packaged continue to confound me. There's aren't enough Picard facepalm memes to express my feelings on the matter.
