无法升级请求库Python

Question

我正在Ubuntu14.04上尝试升级Python2.7.6的请求库，但我做不到。

如果我试图运行sudo pip install requests --upgrade，就会收到以下消息：

Downloading/unpacking requests from https://pypi.python.org/packages/49/df/50aa1999ab9bde74656c2919e

如果我试图将所有的内容重新组合起来，然后重新安装它：sudo pip uninstall requests：

Answer 1

先试试这个

sudo -i pip install --upgrade requests

如果那不起作用，那就低于一

卸载您的pip并安装最新的一个，希望这样可以解决问题。

卸载- sudo pip uninstall pip

重新安装sudo apt install python-pip
