Visual studio代码调试器未与express generator生成的示例express项目连接

npm版本:6.6.0

我已经使用 express --view=jade myapp 在那之后命令 cd myapp/ 和 npm install

现在我正在尝试将vscode调试器附加到这个新创建的项目中,但没有成功。

            "request": "launch",
            "name": "Launch Program",
            "protocol":"inspector",
            "port":3000,
            "program": "/home/pankaj/myfirstapp/myapp/app.js"
        }
    ]
}  

提前谢谢
