如何使ReactNative堆栈跟踪/错误消息更具可读性

Question

我尝试使用ReactNative测试开发，然后我尝试在<br/>组件中添加<Text>（因为它是一个无效的组件），它显示如下：

TypeError: Cannot read property 'Symbol(Symbol.iterator)' of null

在设备上：

有没有办法让你更容易阅读错误（哪一行是问题）？

您应该定义REACT_EDITOR环境变量以允许RN运行您喜欢的文本编辑器。最简单的方法是运行env REACT_EDITOR=atom npm start之类的东西。或者您可以永久设置此变量，只需google how to set environment variable on ${OS}
