title: ModuleNotFoundError: No module named 'django.urls' not working in Django 1.9
body: <p>I'm using Django 1.9</p>
  
  <pre><code> from django.contrib admin
   from django.conf.urls import include, url
   from slack.views import DRSWebhookTransactionView, DRSMessageView
   from django.urls import path 
  
   api_patterns = ([
          path('web/', DRSWebhookTransactionView.as_view()),
          path('events/', DRSMessageView.as_view()),
      ], 'api')
  
  
   urlpatterns = [
          url(r'^admin/', admin.site.urls),
          path('api/v1/', include(api_patterns)),
  ]
  </code></pre>
  
  <p>After running python manage.py runserver:</p>
  
  <pre><code>from django.urls import (  # noqa
  ModuleNotFoundError: No module named 'django.urls'
  </code></pre>
  
  <p>I'm getting this error after I tried including path. If I don't include path it's not showing the error for the 'path', it's still showing the same error. Can someone tell how can I rewrite this program? and tell me what I'm doing wrong? </p>
