尝试在新的 python 安装上安装 pip。我遇到了代理错误。看起来像一个错误get-pip or urllib3??
问题是我是否必须经历设置的痛苦CNTLM 如此处所述 https://stackoverflow.com/questions/14149422/using-pip-behind-a-proxy或者有什么捷径吗？
get-pip.py 文档 http://pip.readthedocs.org/en/latest/installing.html说使用--proxy="[user:passwd@]proxy.server:port"指定代理和相关身份验证的选项。但似乎 pip 传递了整个事情，因为它是urllib3它将“myusr”解释为 url 方案，因为我猜有“：”（？）。

当我在没有用户名和密码的情况下运行命令时，它工作正常，但代理拒绝请求，说它需要身份验证（“407authenticationrequired”）。

我简单地浏览了一下urllib3\poolmanager.py https://github.com/shazow/urllib3/blob/master/urllib3/poolmanager.py而且它似乎与用户名/密码没有任何关系。
