我有一个脚本，用于使用django 1.9.6和mod_wsgi在虚拟机上安装我的应用程序。它用于工作至少一年，然后几个月后我没有使用它 - 它突然不起作用。我总是在一个干净的ubuntu可靠图像上安装，我没有做任何改变。所以我的猜测是apt-get现在正在安装libapache2-mod-wsgi的不同版本。
sudo apt-get update
sudo apt-get install -y python-pip
sudo pip install django=1.9.6
sudo pip install python-social-auth
sudo apt-get -y install apache2 libapache2-mod-wsgi
...
当我尝试运行应用程序时，apache服务器会出错：

我希望在没有实际更改安装脚本以外的任何内容的情况下解决此问题，并且应该可以正常工作，因为它之前有效。
有什么建议吗？

请参阅：
您似乎安装了较新版本的软件包，该软件包具有不同的安装要求，需要安装额外的软件包。
您可能希望将软件包固定为您之前使用的旧版本，否则您可能需要对代码和数据库进行其他更改。
