If you are a Mac OSx user, you will frequently come across installing different packages via terminal. To install python packages, you will need the pip command. By default, Mac OS comes with an older version of python 2.7 due to dependencies. The latest version of packages cannot be downloaded using the pip associated with the old python version.
