I have set the virtual environment having

(website) username[`/public_html/website]

Have django project in /public_html/website directory

When i try to install django using pip install django Gives following error

Collecting django 
Could not find a version that satisfies the requirement django (from versions:)
No mathcing distribution for django

I have tried which pip it gives public_html/website/bin/pip

When I try python manage.py runserver Gives error couldnt import django

How should I install django in virtualenv and then runserver?

EDIT

When tried pip search django got the following error

HTTP error 403 while getting https://pypi.python.org/pypi
