推荐答案
React Native版本0.39存在问题。
There is an issue React Native version 0.39.
您需要在node_modeles / react-native / Libraries / Core / InitializeCore.js中的第30行注释掉'use strict'; ：
You need to comment out 'use strict'; in line 30 in node_modeles/react-native/Libraries/Core/InitializeCore.js:
// 'use strict'; Fix to RN 0.39 - https://github.com/facebook/react-native/issues/11389
或者，您可以返回React Native版本0.38。
Alternatively, you can go back to React Native version 0.38.
