Django can be tricky to install on OS X if you don't use the appropriate tools. I am using OS X 10.10
but any lower version should work.
NOTE:
I assume you have NOT tried to install Python 3 in some other way, if so delete as much as you can (DO NOT DELETE PYTHON 2, THIS IS REQUIRED FOR YOUR SYSTEM TO RUN PROPERLY).
- Install homebrew by running the following:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew doctor
This will show you if everything is gucci. If it's not cool, then attempt to fix the issues.
