我在我的应用 init .py：
中有这一行from .signals import *
当我运行gunicorn myproject.wsgi:application时，它会给我这个错误：

如果我在__init__.py中禁用上述行，则gunicorn将开始工作。
当然，我可以将import行移到另一个地方并解决问题，但我想知道为什么会发生错误，以及是否有另一种解决方法。
答案 0 :(得分：0)
通过使用from .signals import *，您似乎因执行顺序而收到错误。
根据DJANGO_SETTINGS_MODULE的错误，您需要定义以便从模型文件导入。我认为正在发生的问题是当gunicorn加载你的应用程序时，但在Django实际加载了所有应用程序设置之前，__init__.py文件正在执行。
可能的修复方法可能是定义__all__文件中的signals.py。
虽然没有更多的问题背景，但很难知道。
