AttributeError: module 'socket' has no attribute 'AF_UNIX' when connecting google cloud store with django

Question

I am connecting google cloudstore mysql with django using official documentation on app engine environment, given as: https://cloud.google.com/python/django/appengine Firstly, I got the error that mysqlclient 1.3.13 or newer is required. To resolve this issue, I used the solution given on Django - installing mysqlclient error: mysqlclient 1.3.13 or newer is required; you have 0.9.3, but when I do this it gives me the error "AttributeError: module 'socket' has no attribute 'AFX_UNIT'".
