  • 更改配置文件launch.json
    “configurations”: [

          {
              "name":"Launch firefox",
              "type": "firefox",
              "request": "launch",
              "reAttach": true,
              "url": "http://localhost:8080",
              "webRoot": "${workspaceFolder}/vue-cli/plugin-demo/src",
    
          },
    

使用docker中网页版vscode, 启动项目运行时运行路径是:http://localhost:8080(运行服务器IP是10.33.13.12)。

请问是我配置文件写错了吗?运行debug时就一直起不来也不报错
