ReactNative – 未处理的JSexception：SyntaxError
当我试图启动我的RN应用程序在iOS 8我得到这个奇怪的错误： Unhandled JS Exception: SyntaxError
而这一切，没有更多的信息更多。
有没有无意中发现这个问题？
在iOs 9+应用程序运行好，寿。

任何帮助，为什么这个错误发生将非常欢迎！
有一个问题React Native版本0.39。
你需要评论“严格使用”; 在node_modeles / react-native / Libraries / Core / InitializeCore.js的第30行：
// 'use strict'; Fix to RN 0.39 - https://github.com/facebook/react-native/issues/11389
或者，您可以返回到React Native版本0.38。
