Django應用程序在runserver上工作，但在uwsgi上失敗

Question

python3 manage.py runserver工作正常，但在nginx/uwsgi上運行Django應用程序不起作用。 Uwsgi日誌：

During handling of the above exception, another exception occurred:

實際上我在應用程序目錄初始化 .py文件。 並經過設置apps.py和初始化的.py

# apps.py 
from django.apps import AppConfig 

class MistypesConfig(AppConfig): 
    name = 'bookshop' 
    path = '/home/dmitriym/new_pythonworld/bookshop' 

    def ready(self): 
     pass 


# __init__.py 
default_app_config = 'bookshop.apps.MistypesConfig' 

這個問題仍然存在。

問題通過更改權限，允許通過讀取源代碼解決uwsgi用戶。
