I run sudo pip install git-review, and get the following messages:
Downloading/unpacking git-review
C
I had a similar problem, but in my case I was getting the error:
Downloading/unpacking bencode
Cannot fetch index base URL http://c.pypi.python.org/simple/
Could not find any downloads that satisfy the requirement bencode
No distributions at all found for bencode
Storing complete log in /home/andrew/.pip/pip.log
In my case I was able to fix the error by editing ~/.pip/pip.conf and changing http://c.pypi.python.org/simple/ to http://pypi.python.org/simple and then pip worked fine again.
