关于mod_wsgi syntaxError的Django

Question

我在mod_wsgi上安装了带Virtualenv的Django 1.11.5。

python版本是2.7.13。

我在/var/log/httpd/error_log中收到此错误：

[Wed Sep 13 16:41:00 2017] [error] [client 5.125.70.26] mod_wsgi (pid=9606): Target WSGI script '/var/www/html/memit/memit/wsgi.py' cannot be loaded as Python module.

我的Apache虚拟主机是：

<VirtualHost *:80>
    ServerName memit.ir
    ServerAlias www.memit.ir
    DocumentRoot /var/www/html/memit

    WSGIDaemonProcess memit python-path=/var/www/html/memit:/var/www/html/memit/env/lib/python2.7/site-packages
WSGIProcessGroup memit
WSGIScriptAlias / /var/www/html/memit/memit/wsgi.py

    <Directory /var/www/html/memit>
      Allow from all
      Options -MultiViews
      # Uncomment this if you're on Apache >= 2.4:
      #Require all granted
    </Directory>
</VirtualHost>

有什么问题？

如何解决这个问题？
