I am trying to install Python Social Auth for Django, but it is not succesful.
Server OS: Ubuntu 14.04.5 LTS (GNU/Linux 2.6.32-042stab141.3 x86_64)
Python version: 3.4.3
Django version (if it matters): 2.0.8
I use pip install social-auth-app-django
, and the installation is starting, but after a while I get some errors.

What could be done about this?
You are missing ffi headers which are contained in libffi-dev
sudo apt-get install libffi-dev
