ImportError: cannot import name patterns

Question

Python Version: 2.7.5

Django Version: 1.10

When I type nohup python manage.py runserver 0.0.0.0:9001 it shows me

I have googled and someone told me to vi urls.py, but it doesn't work. Another error occurred which shows that cannot import name default.

Answer 1

Use of patterns is deprecated since django 1.8. See docs. You can use plain lists now.

Answer 2

The use of patterns is deprecated in Django1.10. Therefore do not import 'patterns' and your url pattern should be as follows:

from django.conf.urls import include, url

urlpatterns=[
    url(r'^admin/', include(admin.site.urls)),
    url(........),
]

Answer 3

I ran into this error when trying to install Django-Guardian. Instead of downgrading Django, you can install the latest version of Django-Guardian. Try,

pip install 'django-guardian>=1.4.6'

This resolved the issue for me.
