私は以下の警告で同じ問題に直面しました

****************************************************** 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)
