vue2用vscode调试打不上断点

需要设置 sourceMapPathOverrides 首先保证

安装 JavaScript Debugger (Nightly) 插件

vue.config.js 开启 source-map

configureWebpack: {
 devtool: "source-map",
},

 sourceMapPathOverrides 里的路径查询 

在vue网站按 F12 打开开发者工具，选择 Sources

按 Ctrl + P 输入 App.vue，可以查看路径

可以看到路径是 webpack://tt/src/

所以设置 sourceMapPathOverrides 为
 

"webpack://tt/src/*": "${workspaceFolder}/src/*"

  添加调试选择 chrome

 launch.json

    "configurations": [
        {
            "type": "chrome",
            "request": "launch",
            "name": "Launch Chrome against localhost",
            "url": "http://localhost:8080",
            "webRoot": "${workspaceFolder}",
            "sourceMapPathOverrides": {
                 "webpack://项目名/src/*": "${workspaceFolder}/src/*"
            },
        }
    ]
