Question

python3 manage.py runserver工作正常，但在nginx / uwsgi上运行Django应用程序不起作用。 Uwsgi日志：

During handling of the above exception, another exception occurred:

我实际上在应用程序目录中有 init .py文件。设置apps.py和 init .py

之后

# 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'

此问题仍然存在。

和new_pythonworld / wsgi.py

"""
WSGI config for new_pythonworld project.

It exposes the WSGI callable as a module-level variable named ``application``.

For more information on this file, see
https://docs.djangoproject.com/en/1.8/howto/deployment/wsgi/
"""

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "new_pythonworld.settings")

application = get_wsgi_application()

Answer 1

通过更改允许uwsgi用户读取源代码的权限来解决问题。

Answer 2

我遇到了同样的错误，只需在所有应用中添加一个空的 __init__.py 文件即可。

Django应用程序适用于runserver，但在uwsgi上失败
