django-admin runserver 错误（DJANGO_SETTINGS_MODULE 未设置）

Question

我在尝试运行时遇到以下错误

django-admin 运行服务器

PS C:\Users\gasgu\PycharmProjects\djangodennisproj\devsearch> django-admin runserver
Traceback (most recent call last):

我已经用 virtualenv 完成了全新安装，然后我点了 pip install django，创建了项目并运行了 runserver。

我从 pycharm 社区运行它，我读到我还应该设置一个名为 DJANGO_SETTINGS_MODULE 的环境变量，我应该将我的 project.settings 作为值。我这样做了，但我仍然收到错误。

我也从 pycharm 外部尝试了相同的过程，只是使用命令行我仍然得到相同的错误。是不是我做错了什么？

另外请注意：如果我执行“python manage.py runserver”，它会启动服务器。但我不知道这是否应该这样做。

在第一次使用 django-admin 创建项目后，您应该始终使用 manage.py 实用程序，基本上它们是相同的，但 manage.py 具有该项目的设置/配置..所以可以避免这样的问题。如果您使用它的目的更具体..请通知
