This works for me. But I am crazy. - Install Python through Brew. - Upgrade pip using pip. Install all further libraries using pip. Never install Python packages through brew. - Use a plain virtualenv per project/repo. A long time ago I wrote some bash that I keep in my `.bashrc` that overrides the `cd` command. When entering a directory, my little bash script iterates upwards in the directories and activated any virtualenv it finds. I also override the `virtualenv` command to automatically activate the env after creating it. I am aware there are existing tools out there that do this. Pyenv does this right? But I never got used to them and this keeps things simple enough for me. I cannot forget to enter a virtualenv. As I said, I am probably nuts. I also don't use any form of IDE. Just plain VIM.
