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.
