django - 关于 wsgi.py 中 wsgi 模块的 Ubuntu 16.04 服务器错误

Question

我将在虚拟主机的 ubuntu 服务器上设置一个 django 应用程序。
我已经配置了我的虚拟主机，所以出现了一些问题!
但是由于您在此处看到的一些问题，它仍然给我 500 内部错误:

mod_wsgi (pid=31972): Target WSGI script '/var/www/mmcba/mmemp/wsgi.py' cannot be loaded as Python module.

我非常感谢您的回复

更新#2

如果我在 wsgi.py 中使用此代码:

import os

from django.core.wsgi import get_wsgi_application

os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
application = get_wsgi_application()

堆栈跟踪将变为:( mmemp 是我的应用程序的名称):

 mod_wsgi (pid=5579): Target WSGI script '/var/www/mmcba/mmemp/wsgi.py' cannot be loaded as Python module.
 mod_wsgi (pid=5579): Exception occurred processing WSGI script '/var/www/mmcba/mmemp/wsgi.py'.

     application = get_wsgi_application()
   File "/usr/local/lib/python2.7/dist-packages/django/core/wsgi.py", line 13, in get_wsgi_application
     django.setup(set_prefix=False)
   File "/usr/local/lib/python2.7/dist-packages/django/__init__.py", line 22, in setup
     configure_logging(settings.LOGGING_CONFIG, settings.LOGGING)
   File "/usr/local/lib/python2.7/dist-packages/django/conf/__init__.py", line 56, in __getattr__
     self._setup(name)
   File "/usr/local/lib/python2.7/dist-packages/django/conf/__init__.py", line 41, in _setup
     self._wrapped = Settings(settings_module)
   File "/usr/local/lib/python2.7/dist-packages/django/conf/__init__.py", line 110, in __init__
     mod = importlib.import_module(self.SETTINGS_MODULE)
   File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
     __import__(name)
 ImportError: No module named mmemp.settings

我的虚拟主机配置，这里是:

Listen 80

NameVirtualHost 148.251.218.202:80

<VirtualHost *:80>
        ServerAdmin webmaster@mmcba.com
        ServerName mmcba.com
        ServerAlias www.mmcba.com

        WSGIScriptAlias / /var/www/mmcba/mmemp/wsgi.py

        <Directory /var/www/mmcba/mmemp>
        <Files wsgi.py>
        Require all granted
        </Files>
        </Directory>

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

如果您使用 django 1.7+，请替换 wsgi.py 的内容有了这个:

import os

from django.core.wsgi import get_wsgi_application

os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
application = get_wsgi_application()

或尝试将以下行添加到 settings.py

import django
django.setup()
