Python Django设置无法正常工作

我能执行

python manage.py migrate - it executes perfectly

但是当我跑的时候

django-admin shell

它无法给出以下错误

请帮助我无法理解为什么即使migrate命令工作正常，它也无法读取设置

取自：

通常，在处理单个Django项目时，使用manage.py比使用Django admin更容易。如果需要在多个Django设置文件之间切换，请使用Django admin和Django_settings_模块或--settings命令行选项

您没有在

django admin

中指定模块（作为参数），这就是django抱怨的原因。这样做：

django admin shell--settings=myproject.settings

此外，从：

设置模块应采用Python包语法，例如mysite.settings。如果没有提供，django admin将使用django_SETTINGS_MODULE环境变量

您还可以执行以下操作：

您还可以使用

python manage.py shell

和

python manage.py runserver

执行

/manage.py shell
。在
manage.py
文件中，您可以看到它如何设置
DJANGO\u设置\u模块
变量。如果要使用django管理系统命令，则需要导出环境变量（
export-django\u SETTINGS\u MODULE=“manage.py文件中的设置文件路径”
你看不到你在使用另一个命令吗？你应该坚持使用
manage.py
这两个命令。@chirag7jain做了下面的回答帮助你解决了你的问题吗？使用
