今天安装macaca并配置环境，安装ios-deploy的时候报错

npm ERR! code ELIFECYCLE

npm ERR! errno 1

npm ERR! ios-deploy@1.9.4 preinstall: `./src/scripts/check_reqs.js && xcodebuild`

解决方案：

1.网上方案：sudo npm install -g ios-deploy --unsafe-perm=true

尝试还是安装失败，后在stackoverflow中找到答案解决了（链接）如下：

打开xcode中，Preferences > Location > Command Line Tools，选择你的xcode版本之后，

然后就可以安装啦～～sudo npm install -g ios-deploy --unsafe-perm=true

Here is a new Solution, which is working right now.....

You need Download Xcode from APP Store, in X-code go in Preferences > Location > Command Line Tools, then select one of the listed options. After that you can install:

sudo npm install -g ios-sim sudo npm install --global --unsafe-perm ios-deploy
