That gets installed. And then I get:

Okay, that one's easy enough to deal with!
You have something that needs to build a C extension. To do that,
you need to have the Python headers installed. How did you install
Python? On Debian/Ubuntu family Linuxes, that's probably "apt-get
install python3" - so getting the headers would be "apt-get install
python3-dev". Give that a try, and then retry the pip install.
I should have thought about that myself. :-(
An alternative is to switch to Windows and do away with this archaic
concept of users having to build code :)
