每次我使用Expo打开React Native应用程序时，都会在控制台中收到有关该应用程序的元数据的大量消息，但实际上并不能帮助我进行调试。特别是因为每次都具有相同的信息，并且每次重新加载应用程序时都会显示该信息（即使是热加载或实时重新加载）：

如果我正在查看Expo控制台，它以BugReporting extraData:开头，并将以上内容包装在JS对象中。我不知道这是Expo还是React Native消息所独有的，但是无论哪种方式：
有什么方法可以消除此消息？如此之大，以至于发现实际错误变得更加费力。
答案 0 :(得分：2)
我不熟悉Expo，但是最近在一个普通的RN项目中遇到了此日志消息。通过将以下内容添加到索引文件中，我可以将其删除：
console.ignoredYellowBox = ['react-native BugReporting extraData:'];
答案 1 :(得分：1)
我通过添加到项目根目录解决了类似的问题：
const ignoreConsoleMessages = [
'Running "main" with'
]
const origLog = console.log
console.log = (...params) => (
typeof params[0] === 'string' &&
ignoreConsoleMessages.reduce((acc, i) => acc + ~params[0].indexOf(i), 0)
? null
: origLog(...params)
)
