<p>I'm not sure this will fix you original issue, however, at a minimum, you should check the way that you've indicated your Installed_apps:</p>

<p>See Django Docs:  <a href="https://docs.djangoproject.com/en/3.0/intro/tutorial02/#activating-models" rel="nofollow noreferrer">https://docs.djangoproject.com/en/3.0/intro/tutorial02/#activating-models</a></p>

<p>And develop the habit of redacting your SECRET_KEY.</p>


entityMap|blocks|key|729et|text|我刚刚遇到了同样的问题。原来在更新python之后，django-mptt和xlrd模块由于某种原因被卸载了。用pip重新安装它们，现在一切都正常了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2aups|因此，您应该检查已安装的模块，并在必要时重新安装。|d9t33^0|0|0^^$0|$]|1|@$2|3|4|5|6|7|8|F|9|@]|A|@]|B|$]]|$2|C|4|D|6|7|8|G|9|@]|A|@]|B|$]]|$2|E|4|-4|6|7|8|H|9|@]|A|@]|B|$]]]]

<p>I just faced the same problem. Turns out that after updating python, django-mptt and xlrd modules had for some reason become uninstalled. Reinstalled them with pip and everything works now.</p>
<p>So you should check your installed modules and reinstall if necessary.</p>


entityMap|blocks|key|dtcgg|text|检查您创建的urls.py文件是否在正确的位置...我有一个类似的错误，错误，结果是我在应用程序目录之外创建了urls.py。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|av8e0^0|0^^$0|$]|1|@$2|3|4|5|6|7|8|D|9|@]|A|@]|B|$]]|$2|C|4|-4|6|7|8|E|9|@]|A|@]|B|$]]]]

<p>Check if the urls.py file that you created is in the correct place... I had a similar error, error and it turned out that I had created the urls.py outside the app directory.</p>


entityMap|blocks|key|cm49s|text|问题可能出在您的.urls中，特别是如果您正在遵循Django文档，复制代码片段，并且忘记更改URL详细信息以匹配您的应用程序设置。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|70kfu|例如，在我的例子中，我有这个：|8om7u|​|cqlgo|from+django.contrib+import+admin

<p>The problem could be in your .urls especially if you were following the Django documentation, copying the code snippets and forgot to change the URL details to match your application settings.</p>
<p>In my case, for example, I had this:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>from django.contrib import admin
from django.urls import include, path

urlpatterns = [
    path('crime_system/', include('polls.urls')),
    path('admin/', admin.site.urls),
]</code></pre>
</div>
</div>
</p>
<p>Instead of:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>from django.contrib import admin
from django.urls import include, path

urlpatterns = [
    path('crime_system/', include('crime_system.urls')),
    path('admin/', admin.site.urls),

</div>
