我在应用程序的 init.py 文件里有这么一行代码：

from .signals import *

当我运行 gunicorn myproject.wsgi:application 时，出现了这个错误：

如果我把上面提到的那行代码禁用掉，gunicorn 就能正常工作了。当然，我可以把 import 这一行移动到别的地方来解决这个问题，但我想知道为什么会出现这个错误，还有没有其他方法可以解决它。

使用 from .signals import * 这个语句时，似乎是因为执行顺序的问题导致你遇到了错误。

根据关于 DJANGO_SETTINGS_MODULE 的错误提示，你需要先定义这个变量，才能从模型文件中导入内容。我认为出现的问题是，当 gunicorn 尝试加载你的应用时，__init__.py 文件被执行了，但这时 Django 还没有加载完所有的应用设置。

一个可能的解决办法是在你的 signals.py 文件中定义 __all__。

不过，没有更多的上下文信息，很难确定具体问题所在。
