sudo pod install

You cannot run CocoaPods as root

以上答案皆不管用。

楼主，我也遇到同样的问题，昨天更新的cocoapods0.32.1后出
现/Library/Ruby/Gems/2.0.0/gems/claide-0.5.0/lib/claide/command.rb:328:in `help!': [!] You cannot run CocoaPods as root. (CLAide::Help)

接着执行运行：$ sudo gem install cocoa pods

         $ pod install

就好了

sudo rm -fr ~/.cocoapods/repos/master
pod setup
pod repo remove master
pod setup

用上面的代码，原因是cocoapods升级后出现冲突。
如果速度慢的话，且你有gae，给本次的终端设置代理

export http_proxy='http://127.0.0.1:8087'
export https_proxy='http://127.0.0.1:8087'

如果你遇到git证书问题，可以导入gae的证书

git config --global http.sslCAinfo ~/goagent/local/CA.crt

以上

参照这个帖子，我居然奇迹般的好了。怪哉~

先运行 sudo rm -fr ~/.cocoapods/repos/master
然后 pod setup
试试...

直接 $ [sudo] gem install cocoapods 就好了，sudo 可选.

$ sudo gem uninstall cocoapods
$ sudo gem uninstall xcodeproj
$ sudo gem install xcodeproj
$ sudo gem install cocoapods

CocoaPods 在 0.32.0 去掉了 root 权限运行命令。这个问题可能是缓存中有一些需要 root 权限运行的文件，所以试试删除缓存的方法。

先删除全局的缓存：

$ sudo rm -fr ~/Library/Caches/CocoaPods/
$ sudo rm -fr ~/.cocoapods/repos/master/

还不行的话就把当前 Pods 目录清空：

$ sudo rm -fr Pods/

之后再运行：

$ pod install

CocoaPods 的 Troubleshooting 有一段解释：I'm getting permission errors while running pod commands。
