Node Js Debugger 地址已被使用

Question

我是学习 Node Js 的初学者，我正在尝试调试，但遇到此错误：

Waiting for the dError: listen EADDRINUSE: address already in use :::3000
    at Server.setupListenHandle [as _listen2] (net.js:1300:14)
    at listenInCluster (net.js:1348:12)

ebugger to disconnect...

我已经尝试了 PORT 3001 和其他端口，但我仍然遇到同样的错误

这是我的 launch.json 文件：

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "Launch Program",
      "skipFiles": ["<node_internals>/**"],
      "program": "${workspaceFolder}\app.js"
    }
  ]
}

这是我的 app.js 文件

const PORT = process.env.PORT || 3000;
app.listen(PORT, () => console.log(`server started on port ${PORT}`));

Answer 1

使用 npm start 或 yarn start 停止运行应用程序，然后再次尝试调试。您不能运行同时应用和调试。 Node Debugger 会将应用程序运行放入您指定的端口。
