Django-ImportError：没有名为django.core.wsgi的模块

Question

我正在尝试使用Apache和mod_wsgi部署Django应用程序。

我根据以下参考资料安装并配置了它们： -https : //modwsgi.readthedocs.io/en/develop/user-guides/quick-installation-guide.html

https://docs.djangoproject.com/zh-CN/2.0/howto/deployment/wsgi/modwsgi/

django位于/home/zahlen/.local/lib/site-packages

//apache2/apache2.conf

....
....
LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi.so
WSGIPythonPath /home/zahlen/mysite:/home/zahlen/.local/lib/python2.7/site-packages

        Require all granted

//apache2/sites-available/000-default.conf VirtualHost配置

<VirtualHost *:80>

Django和mod_wsgi配置为使用python2.7 。 不使用Vitualenv，Apache使用事件MPM

所有这些都在Ubuntu Server虚拟机上。

//log/apache2/error.log给出以下行来验证python2.7的使用

/home/zahlen/mysite/mysite/wsgi.py

import os,sys
sys.path.append('/home/zahlen/mysite')
sys.path.append('/home/zahlen/mysite/mysite')
sys.path.append('/home/zahlen/.local/lib/python2.7/site-packages')
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")

application = get_wsgi_application()

每次我使用虚拟机的IP地址打开站点时，浏览器都会在主机上引发内部服务器错误

似乎wsgi.py无法导入django软件包，但它存在于/home/zahlen/.local/lib/site-packages/python2.7目录中

谁能告诉我这个问题？

Answer 1

导入Django模块之前，请在wsgi.py设置sys.path 。
