node index.js command start and end server in the same time-CodePudding

I did install WSL2 and ubuntu 22.04 distribution on windows 11. I configured envoirment, installed nvm, node v.16.17.1, next in my folder did npm init, installed express, created index.js file within simple structure:

const express = require('express')
const app = express()
const port = 3000

app.get('/', (req, res) => {
  res.send('Hello World!')
})

app.listen(port, () => {
  console.log(`Example app listening on port ${port}`)
})

When i tap node index.js nothing happen. image

In my second computer with ubuntu 20.04 distribution everything work fine. Does anyone know what to do?

How about doing debugging by referring to https://expressjs.com/en/guide/debugging.html?

like this,

DEBUG=express:* node index.js

If no other problem is found, it would be good to use the --inspect options. https://nodejs.org/en/docs/guides/debugging-geting-started/
