@jarrettj Check out this report #23

You need to install zlib via brew brew install zlib

Then

brew install pyenv
pyenv install 3.7.2

Thank you @aconran. Much appreciated. Should probably be in the docs :).

brew install pyenv
pyenv install 3.7.2

This is the only thing that worked for me; the docs as of today (26/01/2020) didn't lead to a successful install, including with the troubleshooting tips.
