我正在做这个简单的django教程 http://www.madewithtea.com/simple-todo-api-with-django-and-oauth2.html

I was doing this simple django tutorialhttp://www.madewithtea.com/simple-todo-api-with-django-and-oauth2.html

这是我的settings.py文件

This is my settings.py file

我正在使用virtualenv，并且使用此命令来安装django和其他软件包

I am using virtualenv and I used this command to install django and other packages

pip install django django_oauth2_provider djangorestframework markdown django-filter

这是我的urls.py

This is my urls.py

from django.conf.urls import patterns, include, url
from todo import views

urlpatterns = patterns('',
    # Registration of new users
    # TODO
    url(r'^register/$', views.RegistrationView.as_view()),

    # endpoints
    url(r'^todos/$', views.TodosView.as_view()),
    url(r'^todos/(?P<todo_id>[0-9]*)$', views.TodosView.as_view()),

    # API authentication
    # TODO
    url(r'^oauth2/', include('provider.oauth2.urls', namespace='oauth2')),
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')),
)

这是我尝试使用 python manage.py syncdb

Traceback (most recent call last):
  File "/Users/user1/PycharmProjects/todo/my_env/lib/python3.4/site-packages/django/apps/config.py", line 114, in create
    cls = getattr(mod, cls_name)
AttributeError: 'module' object has no attribute 'oauth2'

During handling of the above exception, another exception occurred:

    execute_from_command_line(sys.argv)

    import backends
ImportError: No module named 'backends'

有人可以建议，这是什么问题?
