RN在Github上有比較明確的解決方案，但是對於Xcod不是十分熟悉，沒有一步一步明確的指導，最終在stackoverflow上找到可以解決我的問題的帖子。

If you are using RN 0.46 or above:

There is a breaking change made by Facebook: the location of the script has been changed, more detail here

I was able to solve this error by:

• Opening the project in XCode
• Navigate to Build Phases > Bundle React Native code and images
• Change export NODE_BINARY=node ../node_modules/react-native/packager/react-native-xcode.sh
  to export NODE_BINARY=node ../node_modules/react-native/scripts/react-native-xcode.sh

Notice how packager is now scripts, which is where that file actually lives in latest version of RN

編譯依賴於React Native0.46.4的工程，報錯“react-native-xcode.sh now lives in a different location”
