Olá,

Instalei tudo belezinha no meu Mac, está rodando bem porém toda vez que digito o comando

ionic serve

Aparece as seguintes mensagens

******************************************************
 Dependency warning - for the CLI to run correctly,      
 it is highly recommended to install/upgrade the following:     

 Please install your Cordova CLI to version  >=4.2.0 `npm install -g cordova`
 Install ios-sim to deploy iOS applications.`npm install -g ios-sim` (may require sudo)
 Install ios-deploy to deploy iOS applications to devices.  `npm install -g ios-deploy` (may require sudo)

******************************************************

Quando instalo os dois primeiros pela instrução que ele diz acima tudo bem, porém quando vou instalar o ios-deploy, ele dá o erro abaixo

Qual o motivo disso e como resolver?
