通常，在处理单个Django项目时，使用manage.py比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_MODULE或--settings命令行选项.

Generally, when working on a single Django project, it’s easier to use manage.py than django-admin. If you need to switch between multiple Django settings files, use django-admin with DJANGO_SETTINGS_MODULE or the --settings command line option.

您未指定 -django-admin 中的-settings 模块(作为参数)，这就是Django抱怨的原因.这样做: django-admin shell --settings = myproject.settings .

You didn't specify a --settings module (as an argument) in the django-admin, that's why Django complains. Do it like this: django-admin shell --settings=myproject.settings.

此外，从 docs :

设置模块应采用Python包语法，例如mysite.settings.如果未提供，django-admin将使用DJANGO_SETTINGS_MODULE环境变量.

The settings module should be in Python package syntax, e.g. mysite.settings. If this isn’t provided, django-admin will use the DJANGO_SETTINGS_MODULE environment variable.

您还可以执行 ./manage.py shell
