如何使ReactNative堆棧跟蹤/錯誤信息更具可讀性

Question

我試圖測試使用ReactNative發展，然後我試圖添加<br/>（因爲它是一個無效的成分）一個<Text>組件內部，它顯示了這樣的事情：

TypeError: Cannot read property 'Symbol(Symbol.iterator)' of null 
at launchEditor (/Users/user/Documents/AwesomeProject/node_modules/react-native/local-cli/server/util/launchEditor.js:153:29)

at IncomingMessage.<anonymous> (/Users/user/Documents/AwesomeProject/node_modules/react-native/local-cli/server/middleware/loadRawBodyMiddleware.js:20:5) 

和設備上：

有沒有一種方法，以使其更易於讀取錯誤（該系列有問題）？

您應該定義REACT_EDITOR環境變量以允許RN運行您最喜歡的文本編輯器。最簡單的方法是運行類似env REACT_EDITOR=atom npm start的東西。或者你可以永久設置這個變量，只是谷歌how to set environment variable on ${OS}
