我正在尝试按照官方'Getting Started'Ionic2文档的安装部分中给出的说明设置Ionic2环境。iOs2构建iOs失败
我在装有El Captain 10.11.5版和最新的xCode版本（7.3.1）的Mac上。
在安装Cordova之后，我已经成功执行了命令ionic platform add ios。
当我运行下一个命令ionic emulate ios（作为入门指南中提到的），我得到一个神秘的错误，其日志

然后我上网了一下，找到一个建议，运行以下命令npm install -g ios-deploy --unsafe-perm=true但一旦我这样做，这就是我所获得的
