Installing Flask using Pip

I'm a first timer to Python and I'm trying to set up an easy quick backend with it. When trying to install Flask using Pip I run this and see the following error:

Rutgers-MacBook-Pro:~ rutger$ pip install flask

I also see I've 2 versions of Python:

Rutgers-MacBook-Pro:~ rutger$ py
pydoc             pydoc2.6          python            python2           python2.6         python2.7         pythonw           pythonw2.6
pydoc2            pydoc2.7          python-config     python2-config    python2.6-

Running 2.7 though: 

Rutgers-MacBook-Pro:~ rutger$ python --version
Python 2.7.10

As you can see in the output, the error is

error: [Errno 13] Permission denied: '/Library/Python/2.7/site-packages/itsdangerous.py'

You can try again with sudo pip install flask which lets you run the original command as the root user.
