Found existing installation: six 1.5.2 Cannot uninstall 'six'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial u

今天在制作docker镜像时遇到一个问题，问题描述如下：

Found existing installation: six 1.5.2
Cannot uninstall 'six'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

但是我并没有要安装 six 这个包，经排查发现是因为happybase这个包依赖于six，所以会去安装，但是因为系统也依赖了这个包，如果下载新的就必须卸载旧版本的，但是系统又依赖于旧版本，所以就没有办法卸载，最终导致报错。

不过原因是找到了，但是博主却没有找到完美的解决方案，选择了逃避，自己主动抛弃了happybase，然后结果皆大欢喜～

但是博主希望在你遇到这个问题时能够完美解决～
