javascript - ReactNative - 未处理的 JS 异常 : SyntaxError

Question

当我尝试在 iOS 8 上启动我的 RN 应用程序时，我收到了这个奇怪的错误:Unhandled JS Exception: SyntaxError
仅此而已，没有更多信息了。
有没有人偶然发现了这个问题？
在 iOs 9+ 上，应用程序运行正常。

xCode 版本:8.1。来自 xCode 的日志:

React Native 版本 0.39 存在问题。

您需要在 node_modeles/react-native/Libraries/Core/InitializeCore.js 的第 30 行注释掉 'use strict';:

// '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。
