问题原因

在 CenOS 中，或者其他发行版，我们可以通过 pip 安装 Python 模块，也可以使用 yum 源安装 Python 模块。

也就说，问题可能有两种原因：
1）同个包即通过 yum 安装，也通过 pip 安装，最后导致冲突
2）或者某个模块依赖于更新版本的 pyOpenSSL 模块

从日志中看，可能是 urllib3 模块的问题。

解决办法

下面是原文作者给出的解决方案，能够解决我们的问题：

pip uninstall -y requestsyum reinstall -y python-requestspip uninstall -y sixyum reinstall -y python-sixpip uninstall -y urllib3yum reinstall -y python-urllib3
