在设计DJANGO用户更改密码时，出现NoReverseMatch at /account/password-change/这种妖精如何办？

from django.conf.urls import url
from . import views
from django.core.urlresolvers import reverse

urlpatterns = [
# post views
# url(r'^login/$', views.user_login, name='login'),

url(r'^login/$', 'django.contrib.auth.views.login', name='login'),
url(r'^logout/$', 'django.contrib.auth.views.logout', name='logout'),
url(r'^logout-then-login/$', 'django.contrib.auth.views.logout_then_login', name='logout_then_login'),
url(r'^password-change/$', 'django.contrib.auth.views.password_change',
{'post_change_redirect': '/account/password-change-done/', 'current_app': 'account'},
name='password_change'),
url(r'^password-change-done/$', 'django.contrib.auth.views.password_change_done',
name='password_change_done'),

url(r'^$', views.dashboard, name='dashboard'),
]
