git-hg cannot find mercurial module >= 4.6

Question

When I run git-hg clone I get the error message:

Could not find a python interpreter with the mercurial module >= 4.6 available. Please use the 'PYTHON' environment variable to specify the interpreter to use.

I have a PYTHON environment variable

And the same thing exists in PATH.

What is it looking for?

Answer 1

Installing the mercurial module made it for me:

python -m pip install mercurial
