Using React with Next.js demo is not working

My Package.js

{
  "name": "nextjs",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "dev": "next",
    "build": "next build",
    "prod_start": "NODE_ENV=production node server.js",
    "start": "next start"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "next": "^9.0.2",
    "react": "^16.8.6",
    "react-dom": "^16.8.6"
  }
}

Below is the error log.

Run npm run build first. When you run npm run start, it's trying to start a local server so you can run your app locally. But if you just installed it and haven't yet built your app (as the error indicates), your local server doesn't have anything to serve up.

If you want to run it locally while you're developing (ie, with live reloading), use npm run dev.
