VS代码无法正确设置断点 [英] VS Code Can't Set Breakpoints Properly

问题描述

我正在尝试调试一个很小的项目，但无法使Debugger for Chrome扩展程序完全发挥作用.当我放置一个断点时，它会移到我要调试的功能之外.

I'm attempting to debug a tiny project but I'm unable to get the Debugger for Chrome extension to fully work. When I place a breakpoint it gets moved outside of the function I want to debug.

我正在使用webpack + babel.我的项目托管在.Net平台(特别是DNN)上.

I'm using webpack + babel. My project is being hosted on a .Net platform (specifically DNN).

package.json:

package.json:

{
  "name": "disable-registration",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "build": "webpack",
    "test": "echo \"Error: no test specified\" && exit 1",
    "watch": "npm-watch"
    },
    "babel": {
    "presets": [
      "env"
    ]
    },
    "watch": {
    "build": "src/*.js"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "jquery": "^3.3.1"
  },
  "devDependencies": {
    "babel-core": "^6.26.0",
    "babel-loader": "^7.1.3",
    "babel-preset-env": "^1.6.1",
    "npm-watch": "^0.3.0",
    "webpack": "^4.0.1",
    "webpack-cli": "^2.0.9"
  }
}

launch.json:

launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "chrome",
            "request": "attach",
            "name": "Attach to mickys.dnndev.me",
            "port": 9222,
            "url": "http://www.mickys.dnndev.me/",
            "webRoot": "${workspaceFolder}",
            "sourceMaps": true,
            "skipFiles": ["node_modules"]
        }
    ]
}

确实会设置断点，但是它会完全跳过我的代码.我可以在Chrome开发工具中成功设置一个断点，但是这打破了利用ES6语法的目的.几天来一直在尝试解决此问题，但没有找到解决方案.

The breakpoints that do get set will hit but it completely skips my code. I can put a breakpoint in the Chrome dev tools successfully but that defeats the purpose of taking advantage of ES6 syntax. Been trying to resolve this for days and haven't found a solution.

更新:尝试将我的const值更改为let或var无法解决问题:

Update: tried changing my const value to let or var doesn't resolve the issue:

我现在可以看到它正在尝试调试正确的文件，但是行号不同步.这是我在chrome开发工具中看到的:

I can now see that it is trying to debug the correct file however the line numbers are out of sync. This is what I see in the chrome dev tools:

推荐答案

感谢此帖子我能够解决我的问题.

Thanks to this post I was able to resolve my issue.

我用以下几行创建了一个.babelrc文件:

I created a .babelrc file with these lines:

{
    "presets": ["env"],
    "sourceMaps": "inline",
    "retainLines": true
}

现在达到了预期的断点.是的！

Now breakpoints hit as expected. Yay!

但是，我相信我有一个单独的问题:调试时我没有任何智能感知.我可以查看变量的值，但看不到其他任何文本(函数，关键字等).

However, I believe I have a separate issue: I don't get any intellisense while debugging. I can view the value of a variable but I don't see text on anything else (functions, keywords, etc).

希望这对某人有帮助:)

Hope this helps someone :)
