This looks a lot like you are using Apple's system python. Which 
is probably some python2.7. - No, you say you have python 3.6 
installed. Via pip?

You probably make your life easier to install a fink python. At 
least that's what I have.

Then for me it installs in an expected --user location, i.e.
$HOME/.local/lib/python3.8/site-packages/

~$ pip --version
pip 18.1 from /opt/sw/lib/python3.8/site-packages/pip (python 3.8)
~$ pip install --user hg-evolve

Disclaimer: I don't particularly like pip (except for the 
possibility to uninstall) and build mercurial myself anyway.
