描述
根据基本教程，我无法运行最初的React Native应用程序 . 该错误似乎与UIUserInterfaceIdiomCarPlay有关 .
复制步骤和示例代码
按照这里的教程https://facebook.github.io/react-native/releases/0.23/docs/tutorial.html#content
我创建了一个新的React Native项目 react-native init AwesomeProject 然后进入了该目录，并运行了 react-native run-ios
注意我也试过Xcode，无数修复在线，但仍然没有骰子 . 这是我得到的错误：

Someone最近遇到了与该错误消息
Use of undeclared identifier 'UIUserInterfaceIdiomCarPlay'; did you mean 'UIUserInterfaceIdiomPad'?相同的问题 . 他评论了node_modules/react-native/React/Base/RCTPlatform.m中的第26和27行，显然是让它起作用了 . 它可能与使用过时版本的Xcode有关
