FWIW, I'm not asking about different versions of Python.  I'm asking
about different versions of Python libraries — all of which were
installed for the same version/instance of Python (3.6 in my example).

That was what I was going to do if the "pip --user" method didn't work
well.  In my exaple it's a unix-style command-line utility, so
wrapping it a Bash script that activates the venv should work fine.
