我已经有各种 pod 与我的 Xcode 项目完美配合。我现在尝试通过修改 pod 文件来安装 AFNetwork pod。这是我的新 podfile
platform : ios '7.0'
pod 'MKNetworkKit'
pod 'SBJson', '~> 4.0.0'
pod 'MBProgressHUD'
pod 'STTweetLabel'
pod 'AFNetworking'
但是当我运行命令时
pod update
它抛给我这个问题

我尝试重新安装椰子荚并使用另一个版本的红宝石。
终于通过运行解决了这个问题
gem update --system
gem update cocoapods
pod update
