Unrecognized PORT command

In my localhost, running below command

PORT=4080 node server.js

But, it was throwing an unexpected error.

'PORT' is not recognized as an internal or external command, operable program or batch file.

Do I need to install any module or did I miss any syntax to run it properly?

Once I realised that the issue is it's a linux command, I switch shells to use Git Bash(I'm using Vs-code) and it worked seamlessly. Hoping this is helpful for a newbie that finds the other suggestions daunting.

Install cross-env to support all OS.

npm install --save-dev cross-env
or
yarn add -D cross-env

And finally add cross-env to your command in package.json.

cross-env PORT=4080 node server.js

In Windows you can set scripts in package.json:

Delete set PORT=portnumber &&

and keep it like this :

"start": "react-scripts start"

You can try this way also

 "scripts": {
    "build": "concurrently \"cd client && npm build\" \"cd server && npm build\"",
    "install": "(cd client && npm) && (cd server && npm)",
    "start": "concurrently \"cd client && SET PORT=3000 && npm start\" \"cd server && SET PORT=3001 && npm start\"",
    "start:prod": "cd server && npm start:prod"
  }

In Windows you can set scripts in package.json:

"start": " set PORT=portnumber && react-app-rewired start"

or

"start": " set PORT=3001 && react-script start".

It worked for me:

in package.json file

Here's a moronic way I found to recreate this problem:

  1. Create a npm based app on one system
  2. check it out on another system
  3. FAIL to run npm install
  4. run npm start

Receive error described in question.

Apart from cross-env, Below command can serve the purpose. 

SET PORT=4080 && node server.js

PS: Set environment variable for nodeJs, run command in project folder.

  • Install this additional package cross-env in your node environment. The above command you mentioned is Unix (Ubuntu, Mac, etc…). In the windows environment, you need a different syntax and cross-env does your job.
  • You can also create an .env file with 

PORT=3006

and save it in your project directory.
