Why can't I import folium python package?

I've pip installed folium and get this error when I try to import it in when Im working in my home directory:

---------------------------------------------------------------------------

 ImportError: No module named branca.colormap

However, i can import it when I cd to /Library/Python/2.7/site-packages.... What gives?
