尝试使用pip时出错

Question

我也有同样的错误： Python PIP Install throws TypeError: unsupported operand type(s) for -=: 'Retry' and 'int'

不管我用pip安装什么，我都会得到相同的错误。 系统信息：Linux版本4.4.0-38-generic(地址：lgw01-58)（gcc版本5.4.0 20160609（Ubuntu 5.4.0-6ubuntu1~16.04.2））#57 Ubuntu SMP 2016年9月6日星期二15:42:33 UTC

如果我尝试使用该问题上发布的解决方案，则会出现无法访问的错误：

我确实试着在原始帖子的回复中发表这篇文章，但显然这是错误的做法，它被删除了。在
