折腾好几次，还是这个问题， 仔细想了想这个是在安装了那个 certifi-2016.9.26之后出现的，会不会就是这个库本身的缺陷？
还是先更新到 certifi==2017.4.17 再看看，毫无疑问，肯定就是又会出现那个错误：
pkg_resources.VersionConflict: (certifi 2017.4.17 (/Library/Python/2.7/site-packages), Requirement.parse('certifi==2016.9.26'))然后针对这个问题谷歌，查了好久，看到一个博主说，之前遇到相似的问题，原因就是他的distribute版本太老，尝试升级下这个库版本。
因为本身有安装，所以我们需要指定最新版本或者升级，直接去Pypi看看最新版本是什么？
Pypi地址：https://pypi.org/project/distribute/
看到最新版本是：distribute 0.7.3，所以直接安装
