在Django产品中从Python 2.6升级到Python 2.7

Django版本1.5.2操作系统：Windows

我正在尝试升级我用于Django项目从2.6到2.7的Python。 我在以下文件中做了相应的修改

  1. path设置正确，指向新的Python 2.7
  2. 第三方软件包用python 2.7正确地更新/重新安装
  3. 对* .wsgi文件进行了更改，以包含新安装的第三方软件包
  4. http.conf已更改为WSGIScriptAlias的目录标记

但是，当我试图通过浏览器连接服务器，我收到以下exception

您需要为Python 2.7编译的mod_wsgi的新版本。
