Install and use pip on macOS without sudo / admin access

Most recently tested on macOS Sierra (10.12.6)

1. Download the installation script; curl https://bootstrap.pypa.io/get-pip.py -o ~/Downloads/get-pip.py
2. Run the installation, appending the --user flag; python ~/Downloads/get-pip.py --user. pip will be installed to ~/Library/Python/2.7/bin/pip
3. Make sure ~/Library/Python/2.7/bin is in your $PATH. For bash users, edit the PATH= line in ~/.bashrc to append the local Python path; ie. PATH=$PATH:~/Library/Python/2.7/bin. Apply the changes, source ~/.bashrc.
4. Use pip! Remember to append --user when installing modules; ie. pip install <package_name> --user
