You'll need to install python2 along with pip.
Next, you'll need to install python virtual environment wrapper. You can do so by running pip install virtualenvwrapper.
Now, activate a python virtual environment by running mkvirtualenv ${ENV_NAME}. The ENV_NAME is arbitrary. We'll use "wb" for simplicity.
Finally, run pip install -r requirements.txt to install necessarry dependencies.
When that completes, run ./manage.py migrate --settings=settings.dev to create a local SQLite db instance for developnent.
Finally, run ./manage.py runserver --settings=settings.dev to kick off a dev server.
The dev server will run on localhost:8000 by default. If you prefer another port, just pass the desired port number following the previous command. That is ./manage.py migrate --settings=settings.dev ${PORT}
Note: to deactive the virtual env wrapper, just run deactivate.
