TypeError: 'module' object is not iterable under nginx+uwsgi+django+centos7 Never seen before

I have an annoying problem thest days.There are errors from uwsgi.log in the project I am creating:

Traceback (most recent call last):

File "/root/Envs/magicmall2/lib/python3.6/site-packages/django/core/handlers/exception.py", line 41, in inner File "/root/Envs/magicmall2/lib/python3.6/site-packages/django/core/handlers/exception.py", line 41, in inner Traceback (most recent call last): File "/root/Envs/magicmall2/lib/python3.6/site-packages/django/urls/resolvers.py", line 409, in url_patterns response = get_response(request) File "/root/Envs/magicmall2/lib/python3.6/site-packages/django/core/handlers/base.py", line 172, in _get_response Traceback (most recent call last): iter(patterns) File "/root/Envs/magicmall2/lib/python3.6/site-packages/django/urls/resolvers.py", line 409, in url_patterns TypeError: 'module' object is not iterable

django.core.exceptions.ImproperlyConfigured: The included URLconf 'magic_mall.urls' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.

the project is running fine on my windows laptop.but couldn't work properly while i am deploying on server.
