What does this mean, and why am I getting this error?


Answer: For a system wide pip install you need to do a sudo:

    
    
    sudo pip install fabric
    

Since the system wide packages are available globally, they are written
outside paths that have write permission for a normal user. In that case you
need to do a sudo other permission to write to those folders would be denied
to you.

When installed globally, you can invoke the Python interpreter anywhere in
your system and `import fabric` would be available to you. Also, it would be
available to any user of your system.
