恩，可以把 Nodejs 升级下版本，比如升到 8.x

  node 升级的8.3 以上。今天 测试了一天，最终把node 升级到v8.12.0，react-native-cli 升级到2.0.1，根据中文官方文档换做yarn（v1.9.4）,才顺利跑起来了“react-native  init  imoocApp”命令。之前用npm命令执行到一半卡住不动了，可能翻不了墙网速有关。

  不过执行启动命令有报新的错误了，react-native@0.57.0" 版本是最新的了：
  react-native run-ios
  Found Xcode project imoocApp.xcodeproj
  xcrun: error: unable to find utility "instruments", not a developer tool or in PATH
  
  Command failed: xcrun instruments -s
  xcrun: error: unable to find utility "instruments", not a developer tool or in PATH

      at Promise.resolve.then (/Users/lafa/AppDir/imoocApp/node_modules/react-native/local-cli/cliEntry.js:117:22)
      at <anonymous>
  
  感觉还是有好多坑啊

  后来直接在Xcode中打开项目文件进去了。按报错提示需要先添加开发者账号，然后才开始编译项目，最后成功跑起来了。
