python - Django social_auth doesn't create models -

i'm using django social auth in project, running manage.py syncdb doesn't create required tables in database. tried making new empty project , adding social_auth installed apps didn't work (to find out if package conflics other apps in project or not).

import social_auth works fine means package installed successfully.

i tried deleting tables in database , running syncdb on , over, didn't help.

after logging in , authorizing app error comes up:

programmingerror @ /complete/instagram/ (1146, "table '<my db name>.social_auth_usersocialauth' doesn't exist") 

which implies required tables not created on database.

my installed_apps , result of syncdb:

installed_apps = (     'django.contrib.admin',     'django.contrib.auth',     'django.contrib.contenttypes',     'django.contrib.sessions',     'django.contrib.messages',     'django.contrib.staticfiles',     'social_auth', )  creating tables ... creating table django_admin_log creating table auth_permission creating table auth_group_permissions creating table auth_group creating table auth_user_groups creating table auth_user_user_permissions creating table auth_user creating table django_content_type creating table django_session  installed django's auth system, means don't have superusers defined. create 1 now? (yes/no): no installing custom sql ... installing indexes ... installed 0 object(s) 0 fixture(s) 

ps: used python social auth instead of django social auth , have no problem now, question still exists, why no table created when syncdb called?!
