Having problems installing Heroku database

[Scott Meyers]

Trying to get started with Django. My tutorial tells me to run pip install dj-database-url. When I do that, I get:

postgres@precise64:/vagrant/projects2/microblog$ pip install dj-database-url
Downloading/unpacking dj-database-url
Cannot fetch index base URL http://pypi.python.org/simple/ Could not find any downloads that satisfy the requirement dj-database-url
No distributions at all found for dj-database-url
Storing complete log in /var/lib/postgresql/.pip/pip.log

Any suggestions would be greatly appreciated!
