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/*"},}]
