导入错误：没有名为模型的模块？

Question

我正在使用 Django，并且我的组应用程序不断收到此错误，我已经检查了所有导入设置，一切都很好。我的注册和个人资料应用程序运行顺利，但为什么这个应用程序给我一个模型导入错误？

Traceback (most recent call last):

ImportError: No module named models

Answer 1

因为它认为您引用的是同一目录中的groups.py。 启用绝对导入。

Answer 2

我也遇到了同样的问题。解决方案就像 暗示一样简单

from __future__ import absolute_import

Answer 3

只是猜测，但是您的 models.py 文件是否导入组或装饰器？如果是这样，则存在循环依赖。您需要将其中一个文件中的导入移至函数级别。
