Every time I run pip install on my home laptop pip installs it in to /usr/local/lib/python2.7/site-packages folder. The same pip install command run on another Macbook and pip installs it into /Library/Python/2.7/site-packages folder asking for the root password and it is highly inconvenient. 
Question: What needs to be done in order to configure the second laptop so pip installs the modules into the /usr/local/lib/python2.7/site-packages folder.
