解决方法：在 终端执行如下命令 sudo xcode-select -s /Applications/Xcode.app/Contents/Developer/

注意：前提是你已经安装了xcode

pod 'GLog', :podspec => '../node_modules/react-native/third-party-podspecs/GLog.podspec'  

2.导入yoga 开发库 运行iOS工程会报错

 导入yoga 开发库   运行iOS工程会报错    Implicit conversion loses integer precision: 'size_type' (aka 'unsigned long 之类的问题   

解决：在podfile文件里加入第三方库警告忽略

pod "yoga", :path => "../node_modules/react-native/ReactCommon/yoga"

然后可以正常运行iOS工程了
