Question

当我运行python manage.py migrate命令时，出现以下堆栈跟踪消息“ SECRET_KEY设置不能为空”错误。但是，我在我的settings \ local.py文件中设置了SECRET_KEY，并且我正在使用py manage.py runserver --insecure --settings=locallibrary.settings.local命令来运行django应用程序。

我缺少什么（希望这不是新手的错误）？

Answer 1

将空白__init__.py文件添加到locallibrary\settings路径

然后通过python manage.py runserver --insecure --settings=locallibrary.settings

运行管理命令

Answer 2

我能够通过将wsgi.py和manage.py文件更改为将'DJANGO_SETTINGS_MODULE'指向'locallibrary.settings.local'而不是'locallibrary.settings'来解决这个问题
