打包升级后，Pip在Ubuntu 14.4上坏了

我试图在EC2 ubuntu 14.4实例上升级python请求包。 这样做之后，哪个没有抛出我跑的错误

pip freeze 

并得到：

正如你可以看到我试图卸载并以各种方式重新安装点无济于事。 我怎样才能再次工作？

编辑：

• 我怎样才能加载一个字体文件与PIL.ImageFont.truetype没有指定绝对path？
• Python“pip安装”失败与AttributeError：“模块”对象没有属性“SSL_ST_INIT”
• 主pipe安装后无法识别的服务问题
• cron作业不会输出到nohup.out
• /usr/local/lib/python2.6和/usr/lib/python2.6有什么区别？
