python - 引发 NoReverseMatch(msg) django.urls.exceptions.NoReverseMatch : Reverse for 'login

Question

我正在尝试添加我单独制作的用户应用程序，然后尝试将其添加到我的博客中。但问题是每次我尝试添加这个东西都会搞砸，就像我现在遇到的这个错误一样。

raise NoReverseMatch(msg) django.urls.exceptions.NoReverseMatch: Reverse for 'login' not found. 'login' is not a valid view function or pattern name.

so far i have done this

blog/urls.py

# from users import views as user_views
from posts.views import index,postDetail, categoryDetail, blog, search

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', index, name="home"),
    path('blog/', blog, name="blog"),
    path('search/', search, name='search'),
    path('<slug>/', postDetail, name='post-detail'),
    path('category/<slug>/', categoryDetail, name='category-detail'),
    path('login/', login_view),
    path('logout/', logout_view),
    path('register/', register_view),
    # path('register/', user_views.register, name='register'),
    # path('login/', auth_views.LoginView.as_view(template_name='users/login.html'), name='login'),

# path('login/', auth_views.LoginView.as_view(template_name='users/login.html'), name='login'),

此网址已被注释掉，并且您没有任何其他 name="login"。
