我尝试这样做tutorial，但是我有一个问题。它引起了另一个版本的Django。我在论坛上看到过很多类似的话题，但我无法将它们与我的情况相匹配。
当尝试在以下文件中启动“ http://127.0.0.1:8000/accounts/login/”时，我会在消息“ / accounts / login /”中看到消息“ NoReverseMatch”。

然后我尝试在以下位置更改urls.py中的代码：
from django.contrib import admin
from django.urls import path, include
app_name = 'auth'
urlpatterns = [
path('reviews/', include('reviews.urls', namespace="reviews")),
path('admin/', admin.site.urls),
path('accounts/', include('django.contrib.auth.urls', namespace='auth'))
]
但是CMD返回一条消息：
'Specifying a namespace in include() without providing an app_name '
我试图更改login.html和urls.py中的代码，但效果也不佳。
'<li><a href="{% url 'login' %}">Login</a></li>' (login file)
'path('accounts/', include('django.contrib.auth.urls', namespace=auth))' (urls file)
我认为该错误是由应用程序的名称引起的（'app_name ='auth'）。我如何给他们正确的名称（如果我的HTML文件不在任何应用程序中间）？或者我该如何解决我的错误？
编辑（下一个测试1）
好吧，下面我写了我的步骤：
1。）我在base.html中对此进行了更改：
<li><a href="{% url 'logout' %}">Logout</a></li>
这：
<li><a href="{% url 'login' %}">Login</a></li>
2。）我将使用http://127.0.0.1:8000/accounts/login/

编辑（下一个测试2）
好吧，如果显示html更改后出现错误（'auth'未注册），我尝试添加'namespace ='auth'。
1.1）我正在从以下方式更改urls.py文件：
urlpatterns = [
...
path(r'accounts/', include('django.contrib.auth.urls'))
]
对此：
urlpatterns = [
...
path(r'accounts/', include('django.contrib.auth.urls', namespace='auth' ))
]
1.2）尝试启动服务器和CMD（命令行）会返回信息
'Specifying a namespace in include() without providing an app_name '。
1.3）好吧，我尝试添加app_name：
app_name='django.contrib.auth' #or only 'auth'
urlpatterns = [
...
path(r'accounts/', include('django.contrib.auth.urls', ))
]
1.4）她仍然返回“在include（）中指定一个名称空间而不提供app_name”。在这里，我不知道该怎么办。
