django增加用户认证模块时，总是提醒模块的url.py中 url(r'^login/$', 'django.contrib.auth.views.login', name='login'),出错：
TypeError: view must be a callable or a list/tuple in the case of include().
解决办法：改为下面的写法
from django.contrib.auth.views import login
...
url(r'^login/$', login, name='login'),
...
原因：
django1.10不再支持 url(r'^login/$', 'django.contrib.auth.views.login', name='login'),这种用法；
