I can imagine, I didn't expect it to be easy :)

If I am not mistaken then you would need to have Python 2
installed on your system in order to set up a `virtualenv`
or `pyenv` with Python 2. Assuming that we are targeting a
scenario in which this is not the case anymore, those two
paths would not help.

The docker approach is a nice idea :) and as long as there
are containers that come with a Python 2 interpreter it
should work.
