I have the latest version of pip 8.1.1 on my ubuntu 16. But I am not able to install any modules via pip as I get this error all the time.
File \"/usr/local/
if you have 2 versions of pip for example /usr/lib/pip and /usr/local/lib/pip belongs to python 2.6 and 2.7. you can delete the /usr/lib/pip and make a link pip=>/usr/local/lib/pip.
/usr/lib/pip
/usr/local/lib/pip
