VSCodedebuggingNode.js与debugging适配器中的ES6未处理的错误
我正在使用Visual Studio代码来debugging用ES6编码的Node.js程序。
我使用babel来编译ES6到ES5，并且一切正常，代码工作正常，当我运行它没有debugging。
说到debugging，出现了一个问题。
有3个文件：
index.js
import hello from './imported'; import hello2 from './imported2'; const h = hello(); const h2 = hello2() console.log(h); console.log(h2); imported.js
function hello() { return 'hello world'; }; export default hello;
imported2.js
function hello2() { return 'hello world again'; } export default hello2;
这是我的launch.js
{ "version": "0.2.0", "configurations": [ { "type": "node", "request": "attach", "name": "Attach", "port": 5858 }, { "type": "node", "request": "launch", "name": "Launch Program", "program": "${workspaceRoot}/build/index.js", "sourceMaps": true } ] }
是的，我正在使用源地图，以便断点可以停止在源文件。
我在程序中放置了3个断点：
- index.js
const h = hello(); - import.js
return 'hello world'; - imported2.js
return 'hello world again';
当我启用所有3个断点时，所有的断点工作正常，当我禁用第一个断点，发生错误，debugging控制台打印：

看来程序工作正常，但断点不生效。
当我启用最后两个断点时，如何使断点工作？
我在用：
- Visual Studio Code Version 1.16.1（1.16.1）
- 节点-v v8.5.0

快速浏览一下，这里是关键：
如果将启动configuration的outFiles属性设置为指向磁盘上的这些文件，则应该能够提前加载源映射。
