当我运行django-admin migrate时，我收到以下错误：

Traceback (most recent call last):

django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

admin上的相同命令; py：python admin.py完美无缺。我想这意味着我可以使用admin.py，但我想了解为什么django-admin找不到我应用的移民。它使用的过程是什么？可能是什么问题？

您收到错误，因为在运行django-admin时，它不知道要使用哪个设置模块。您可以按照错误消息中的建议通过环境变量指定它，或者只在项目中使用manage.py。

django-admin是Django用于管理的命令行实用程序   任务。

此外，在每个Django中自动创建manage.py   项目。 manage.py与django-admin做同样的事情，但要小心   为你做的一些事情：


它将您的项目包放在sys.path上。

设置DJANGO_SETTINGS_MODULE环境变量，使其指向项目的settings.py文件。

Django在从django-admin运行命令时配置异常，但不管理manage.py
