Too bad it's only for Python3 and installing both 2 and 3 is complicated. Would be a good program if it supported python2.

There are several tools that make having both python 2 and 3 running trivial. Pipenv and conda are probably the two better ones. On the whole you should probably using one of them even if all your development is done with the same python version

pyenv

pipenv is dependency management on top of that

What issues are you having? Installing 2 and 3 side by side on most platforms is trivial.

I used to think like this, until I saw a lab where stem cell research is done. The scientists were carrying around a tray of harvested baby organs.
