To run your app on iOS:

   react-native run-ios

   - or -

   Open ios/RWBuy.xcodeproj in Xcode

   Hit the Run button

To run your app on Android:

   Have an Android emulator running (quickest way to get started), or a device connected

注意：React Native升级后创建项目出现问题的处理方案

报错 ：Cannot find module 'invariant'

解决方案：

原来是新版本的cli构建工具更新的时候，要同时更新npm的版本。

sudo npm  update npm -g
