Installing virtualenvwrapper if you need to

If you see a command not found error when trying to run mkvirtualenv, here's how to fix it.

We install virtualenvwrapper for all new users by default. If you've got an older pythonanywhere account, it's easy to install virtualenvwrapper:

echo '' >> ~/.bashrc && echo 'source virtualenvwrapper.sh' >> ~/.bashrc
source virtualenvwrapper.sh

Once you've added the virtualenvwrapper command to your .basrhc, mkvirtualenv and all the other tools will be available in all your bash consoles.
