解决：

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

卸载老版本cocopods，执行下面命令，

可能会出现多个版本的cocoapods，可以选择一项一项的删除，也可以选择最后一项全部删除

sudo gem uninstall cocoapods

执行下面命令删除全局的缓存

sudo rm -fr ~/Library/Caches/CocoaPods/

查看本地安装过的cocopods相关东西

gem list --local | grep cocoapods

然后使用命令逐个删除

$ sudo gem uninstall cocoapods-core

$ sudo gem uninstall cocoapods-deintegrate

安装CocoaPods, 这里默认你的brew和ruby已经安装好了

sudo gem install cocoapods

OS X 10.11以后系统的安装cocoapods 指令：

sudo gem install -n /usr/local/bin cocoapods
