错误 :: CocoaPods 已安装但无法工作。您似乎已安装 CocoaPods，但无法工作

Question

CocoaPods installed but not working.
        You appear to have CocoaPods installed but it is not working.
        This can happen if the version of Ruby that CocoaPods was installed with is different from the one being used to invoke it.
        This can usually be fixed by re-installing CocoaPods.
