Would it be possible to also change the install command to use "python
-m pip" rather than "pip"? On Windows, if the install upgrades pip,
that will attempt to replace the running pip.exe wrapper, which will
then fail because it's in use by the OS. Using "python -m pip" avoids
this issue and is portable. It's a minor point, but it saves a hard to
diagnose error (it took me a while to work out what was going on, and
I am very familiar with this issue!!!)
