最近因为手贱自己用终端来清除缓存，不小心弄坏了系统，虽然没啥重要资料，但是重装挺麻烦的，大家一定要做好备份....下面是我遇到的问题在安装Cocoapods的时候遇到这样的报错
然后我在网上找了下，发现这篇博文 pod安装失败，Operation not permitted - /usr/bin/pod
进去看了下，用第一种方法试了下
这样操作完后继续sudo gem install cocoapods，还是报错如第一张图，实在没办法了，有人遇到过这种情况么，求解
学习是最好的投资！

➜ ~ sudo gem install -n /usr/local/bin/ cocoapods 试试这一句,亲测有效
