Ubuntu 16.04 服务器错误关于 wsgi.py 中的 wsgi 模块

Question

我要在虚拟主机的 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，以便出现问题！
但是由于您在此处看到的一些问题，它坚持给我 500 个内部错误：

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'.

self._setup(name)

self._wrapped = Settings(settings_module)

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 [e-mail]
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>

Answer 1

如果你使用的是 django 1.7+，请用这个替换wsgi.py的内容：

import os
from django.core.wsgi import get_wsgi_application
os.environ['DJANGO_SETTINGS_MODULE'] = 'myapp.settings'
application = get_wsgi_application()

或者尝试将以下行添加到settings.py

import django
django.setup()

这里还有一个类似的问题。希望对您有所帮助。

解决方案：
将项目和应用程序目录添加到 sys.path 中 wsgi.py 中，它将起作用。
它适用于应用中的每个未知模块

import sys
sys.path.append('<Project_Directory>')
sys.path.append('<Project_Directory>/AppName')
