我刚安装了Django并尝试第一次运行它。
目前为止,我所做的只是执行了pip3 install Django
和django-admin startproject
命令。
在安装完后,我运行了manage.py check
和django-admin check
命令。其中,manage.py check
没有显示任何问题,但django-admin check
命令的输出结果如下:
django.core.exceptions.ImproperlyConfigured: Requested setting ROOT_URLCONF, but settings are not configured.
You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before
accessing settings.
我知道我需要编辑DJANGO_SETTINGS_MODULE
环境变量,但是:
- 它的值应该是什么,它应该在何时/如何设置?
- 我可能做错了什么导致出现这个错误?
更新
运行django-admin check --settings=djangotest.settings
解决了django.core.exceptions.ImproperlyConfigured
错误。
现在我有一个新的ModuleNotFoundError: No module named 'djangotest'
错误。确实,djangotest
是我的项目名称。我检查并找到了我的设置文件。它如下所示:

为什么django-admin找不到这个文件,该怎么解决?
