Answer 1

解决办法是改变操作系统环境设置默认值“在管理.py收件人：

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'toneapp.settings.dev_settings')

Answer 2

在你的层次结构中，你有独立的settings.py，比如base_settings.py和dev..和production...，所有的都放在设置文件夹中。你知道吗

toneapp/
    settings/
      __init__.py
      base_settings.py
      dev_settings.py
      production_settings.py

简单地说，您已经更改了Django的默认层次结构，这就是出错的原因，因为当Django搜索toneapp/settings.py时，它找不到它。最简单的解决方案是返回到默认层次结构并合并settings.py中的所有设置，否则，您必须搜索并更改Django调用settings.py的方式，并将其调整为您的方式。你知道吗
