【问题描述】：

我正在尝试运行 manage.py 服务器，但它遇到了一些错误！我只是想在网络上打印你好，但它不起作用

(venv) ubuntu@node:~/PycharmProjects/Oin$ python manage.py runserver
Performing system checks...

    During handling of the above exception, another exception occurred:

如果您想要任何 .py 文件，请随时询问谢谢！我的项目目录：https://github.com/shreekantbatale2/Oinn

【问题讨论】：

看起来您的settings.py 文件有问题，或者您进行了循环导入。但是没有任何细节，很难知道确切的问题是什么。
嗨@Shree - 请让我们看看你的项目的目录和文件结构。
嗨@MichealJRoberts，这是我的项目目录->github.com/shreekantbatale2/Oinn
@Shree 请查看我的新答案，如果这有帮助，请告诉我...
@ShreeBatale 嗨 Shree，我的正确答案已被删除，而您所说的问题被标记为正确答案，这是有原因的吗...

标签： python django pycharm

【解决方案1】：

您的urls.py 文件中似乎需要这两个选项之一：

from django.urls import path

from . import views

urlpatterns = [
    path('', views.index, name='home')
]

或者，如果您使用的是 url 调度程序，更有可能考虑到您的 urls.py 文件中的内容：

from django.conf.urls import url

from . import views

urlpatterns = [
    url(r'^', views.index, name='home')
]

【讨论】：

嘿，谢谢，它工作正常。你能告诉我这两个选项有什么区别1）url（r'^'，views.index，name ='home'）和2path（''，views.index，name ='home'）是什么r在这里？
@ShreeBatale 太棒了 - 如果你还没有这样做，请也给它投赞成票 :) 我相信这是 Django 2.0 + 其中path（和re-path）的一个变化现在是首选选项（使用re_path() 匹配正则表达式）。请参阅docs.djangoproject.com/en/2.1/topics/http/urls 了解更多信息。 url()仍然可以在 Django 中使用，它更像是一个向后兼容的选项，因为有很多教程在 urlpatterns = [] 中使用了 url()。
@ShreeBatale 你也能接受这个答案吗:)
不用担心 :) 希望它是有道理的——当你想了解事物时，绝对总是加倍使用最新的文档。（顺便说一句，我相信你的 urls.py 文件中应该有 urlPatterns，而它应该是 urlpatterns。

【解决方案2】：

在您的仓库中
进行以下更改：
在 openin/urls.py 文件中：
你拼错了urlpatterns（你编码了 urlPatterns）
在文件 Oin/urls.py
path('^$', include('openin.urls')),
致
path('', include('openin.urls')),

【讨论】：

这不是工作伙伴：/ Micheal 已经给出了答案，它对我来说工作得很好，无论如何感谢编码器:)
