执行pod指令出错：Traceback (most recent call last):

今天第一天wfh，需要远程拉代码，拉到后需要pod install，但是家里mbp的pod version太低，然后需要升级cocoapods，但是发现ruby version太低，又要升级ruby，好不容易ruby升级成功了，然后更新cocoapods，本以为成功了，但当我输出pod --version的时候，一直都是老版本的version！？
OS：我明明看到succeed了啊！！why？？
于是我就开始一顿百度谷歌，最后在一个同事的帮助下发现了，原来pod一直读的都是老ruby的pod，于是我就想卸载老的ruby，但他一直提示卸载不了，终于我忍不了了，直接把老ruby中的一个pod可执行文件删除了，于是就出现了这一幕，当我再想要输出pod --version的时候就无法到pod的代码了

DsssssdeMacBook-Pro:Mey a10.12$ pod --version

在我不断卸载重装cocoapods之后，我偶然发现了简书一位大佬的log，我直接就是直呼yyds决绝子！！！！！直接就是一个解决，两行命令，分享给大家

1、sudo gem update --system
2、gem install cocoapods

大佬blog直通车在这里

另外，rbenv比rvm好用多了，同事说的，我用了之后直呼内行！！！真奈斯啊！！！
