我还没有发现这个来自Google的任何引用，但我在几十个AWS EC2 CentOS实例上遇到了这个问题。 如果awscli不存在，awscli会安装正常。 但是，从v1.4.3开始，任何升级到> = 1.4.4（ 'pip install --upgrade awscli' ）的'pip install --upgrade awscli'导致以下错误：

然后，从/root/.pip/pip.log：

在aws版本升级1.4.3 – > 1.4.4,1.4.3 – > 1.5.0和1.4.4 – > 1.5.0的计算机上出现相同的错误。
事实certificate，如果我试图直接升级它们，那么awscli还有其他的依赖关系，如果我试图直接升级它们，每个失败的基本问题都是一样的。 我不确定究竟是什么问题，但删除/tmp/pip-build-root文件夹修复了所有问题。
