ubuntu - PIP Could not find any downloads that satisfy the requirement SQLAlchemy

Question

• Ubuntu 12.04
• Apache 2.2.22

pip has stopped working on my ubuntu server and gives the below error when I try to download anything.

$ sudo pip install SQLAlchemy
Downloading/unpacking SQLAlchemy
  Cannot fetch index base URL http://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement SQLAlchemy
No distributions at all found for SQLAlchemy
Storing complete log in /home/user/.pip/pip.log

All of the below also do not work

$ sudo pip install --upgrade pip 
$ sudo apt-get install build-essential

My /etc/environment has the below settings which were working previously.

http_proxy="http://myproxyhere:portnumberhere/"
HTTP_PROXY="http://myproxyhere:portnumberhere/"

Has anyone got any idea what might be going wrong?

Answer 1

Answer: upgrade pip.

I had version 1.1 installed. With sudo pip install --upgrade pip I got version 8.1.2 and the package I wanted installed properly.
