Question

尝试将模型导入我的Google应用引擎应用时，我收到以下错误：

Traceback (most recent call last):
  File "/base/data/home/runtimes/python27/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 240, in Handle
handler = _config_handle.add_wsgi_middleware(self._LoadHandler())
  File "/base/data/home/runtimes/python27/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 299, in _LoadHandler
handler, path, err = LoadObject(self._handler)
  File "/base/data/home/runtimes/python27/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 85, in LoadObject

from user.database import u_db
ImportError: cannot import name u_db

我重命名了模型文件及其容器文件夹，并且可以看到这与Path有关。

我很感激在解决这个问题时给予了一些帮助，因为我被困住了。

感谢。

您的模型中存在循环依赖关系，请参阅回溯中的这些代码：

  File "/base/data/home/apps/app/0-1.405524594589080344/BaseHandler.py", line 26, in <module>
from user.database import u_db

...

  File "/base/data/home/apps/app/0-1.405524594589080344/events/database/e_db.py", line 7, in <module>
from user.database import u_db

你需要解决这个问题。通常只需将import语句移动到实际需要的函数内而不是仅仅放在文件的顶部即可。但并非总是如此。
