python - 在 Django 产品中从 Python 2.6 升级到 Python 2.7

Question

Django 版本 1.5.2操作系统 : Windows

我正在尝试将用于 Django 项目的 python 从 2.6 升级到 2.7。我对以下文件做了相应的修改

1. 正确设置路径以指向新的 python 2.7
2. 第三方包已正确更新/重新安装 python 2.7
3. 更改 *.wsgi 文件以包含新安装的第三方包
4. http.conf 已更改为 WSGIScriptAlias 的 Directory 标签

但是当我尝试通过浏览器连接服务器时，出现以下异常
