Javascript 设置react native—；无用的错误消息

我在设置我的React Native项目时有点不知所措

模拟器呈现开始/加载页面，但随后无法呈现index.ios.js

我在Xcode控制台中接收到以下错误，并且在故障排除方面没有运气：

2015-10-05 14:02:40.995 [info][tid:com.facebook.React.JavaScript] 'Failed to print error: ', 'Requiring module "ExceptionsManager" which threw an exception'
2015-10-05 14:02:40.998 [info][tid:com.facebook.React.JavaScript] 'Failed to print error: ', 'undefined is not an object (evaluating \'require(\'ExceptionsManager\').handleException\')'
2015-10-05 14:02:41.036 [info][tid:com.facebook.React.JavaScript] 'Failed to print error: ', 'Requiring module "ExceptionsManager" which threw an exception'
2015-10-05 14:02:41.038 [info][tid:com.facebook.React.JavaScript] 'Failed to print error: ', 'undefined is not an object (evaluating \'require(\'ExceptionsManager\').handleException\')'

在chrome开发工具调试器ui中，我遇到以下错误：

Failed to print error:  Requiring module "Promise" which threw an exception —InitializeJavaScriptAppEngine.js:43
Failed to print error:  Requiring module "ExceptionsManager" which threw an exception — InitializeJavaScriptAppEngine.js:43
Failed to print error:  Cannot read property 'handleException' of undefined

如果任何人都熟悉这些错误，我们将非常感谢您的帮助

谢谢

您解决过这个问题吗？今天我自己发现了它，它有点神秘。@pbattison重新安装react native对我有效，我不知道为什么，但我必须在这个特定的项目上时不时地这样做。
