Python raise NoReverseMatch（msg）django.url.exceptions.NoReverseMatch:与#x27相反；登录

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时，我都会遇到这样的错误

提升NoReverseMatch（msg） django.URL.exceptions.NoReverseMatch:找不到“登录”的反向“登录名”不是有效的视图函数或模式名称

到目前为止，我已经做到了这一点

blog/url.py

users/forms.py

users/views.py

此url已被注释掉，您没有任何其他url具有

name=“login”

---

此url已被注释掉，并且您没有任何其他url具有

name=“login”

您尚未为登录url命名

path('login/', login_view, name='login'),

---

您尚未指定登录url的名称

path('login/', login_view, name='login'),

---

我认为只有当你使用基于类的视图时才使用这个，这就是为什么我评论这个，并且只使用基于函数的视图创建新的。我认为只有当你使用基于类的视图时才使用这个，这就是为什么我评论这个，并且只使用基于函数的视图创建新的。
