Just a note to say I did, in fact, succeed with:

PS> $env:JYTHON_OPTS='-Dcpython_cmd=C:\Python\2.7.15\python.exe'
PS> pip install mpmath

and with sympy as a whole, and the equivalent on Linux:

$ export JYTHON_OPTS="-Dcpython_cmd=python"
$ pip install mpmath

If we like this answer, then it is a documentation (error message) change only.

All our other properties are namespaced to python.*: I was wondering about python.c.python, or python.cpython2, or similar for consistency?
