    'django_extensions',
)

run command

You also need `pygraphviz` installed. – Forge Mar 03 '16 at 11:29

If you're on OSX: 1. `brew install graphviz`, 2. `pip install pygraphviz`, 3. `pip install django-extensions` – aralar Oct 13 '16 at 18:55
for ubuntu: ```apt-get install libgraphviz-dev``` was required before pip install – Cuyler Quint Jun 30 '21 at 17:58
