如何在VSCode编辑器中调试NodeJS(ES6)代码? [英] How to debug NodeJS(ES6) code in VSCode editor?

问题描述

我正在尝试从VSCode调试用ES6编写的nodejs应用程序. 但这会引发以下错误:

I am trying to debug my nodejs application written in ES6 from VSCode. But it is throwing following error:

node --debug-brk=18712 --nolazy index.js

我查看了如何调试vue 和

I have looked at How do I debug vue js application in VS Code? and https://medium.com/@katopz/how-to-debug-es6-nodejs-with-vscode-8d00bd6c4f94#.yaevayjs3 but those solutions are not working.

我的package.json:

My package.json:

{
  "name": "ntask-api",
  "version": "1.0.0",
  "description": "Task list API",
  "main": "index.js",
  "scripts": {
    "start": "babel-node index.js"
  },
  "author": "Siva",
  "dependencies": {
    "babel-cli": "^6.5.1",
    "babel-preset-es2015": "^6.5.0",
    "consign": "^0.1.2",
    "express": "^4.13.4",
    "sequelize": "^3.19.2",
    "sqlite3": "^3.1.8"
  },
  "devDependencies": {
    "babel-register": "^6.18.0"
  },
  "babel": {
    "presets": [
      "es2015"
    ],
    "sourceMaps": true,
    "retainLines": true
  }
}

launch.json:

launch.json:

{

    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Launch Program",
            "program": "${workspaceRoot}/index.js",
            "cwd": "${workspaceRoot}",
            "sourceMaps": true
        },
        {
            "type": "node",
            "request": "attach",
            "name": "Attach to Process",
            "port": 5858
        }
    ]
}

我了解我使用 babel-node 从控制台正常运行应用程序以使用ES6，但是如何让VSCode使用 babel-node 而不是节点?

I understand that I am using babel-node for running the application normally from console to use ES6, but how to let VSCode use babel-node instead of node?

推荐答案

您需要将launch.json配置文件中的runtimeExecutable设置为babel-node的路径值.

You need to set runtimeExecutable in launch.json configuration file to the value of babel-node's path.

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Launch via Babel",
            "program": "${workspaceRoot}/index.js",
            "runtimeExecutable": "${workspaceRoot}/node_modules/.bin/babel-node",
            "cwd": "${workspaceRoot}"
        }
    ]
}
