Why do I need to use pip3 but not pip
When I read this https://pip.pypa.io/en/stable/installing/ it says I have the pip installed when I installed the python from official doc. But when I run the `pip` command from shell, I get error, but pip3 works.
? pip --version
zsh: command not found: pip
? pip3 --version
pip 18.1 from /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pip (python 3.7)
Do I always need to install using pip3 program then?
