    from django.conf.urls import patterns, include, url
ImportError: cannot import name patterns
Performing system checks...

这是我的urls.py

from django.conf.urls import patterns, include, url
from django.contrib import admin

urlpatterns = patterns['',
    url(r'^admin/', admin.site.urls),
    url(r'^hello/$', 'blog.views.hello'),
    url(r'^hello_template/$' , 'blog.views.hello_template'),
]

我该如何解决这个问题

较新版本的Django（如您所使用的1.10）不使用patterns。只需将网址放在列表中即可。您还需要导入将处理每个URL的视图函数，并将这些函数作为参数提供而不是字符串：

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^hello/$', views.hello),
    url(r'^hello_template/$' , views.hello_template),
]

请参阅https://docs.djangoproject.com/en/1.10/topics/http/urls/#example
