NameError: name 'patterns' is not defined

[Debian]

Hello guys,

I'm trying to install graphite with Grafana Documentation but when i try to do the following command i get the error:
  

 django-admin.py migrate --pythonpath /opt/graphite/webapp --settings graphite.settings
File "/opt/graphite/webapp/graphite/urls.py", line 29, in <module>
    urlpatterns = patterns('',
NameError: name 'patterns' is not defined

I tried to modify the the line in /opt/graphite/webapp/graphite/urls.py:

 from django.conf.url.defaults import *

to
from django.conf.urls import *
or to
from django.conf.url.defaults import  url, include, patterns 

But still not working, any ideas please.

Thanks.
