In my localhost, running below command

PORT=4080 node server.js

But, it was throwing an unexpected error.

\'PORT\' is no

Answer 1

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"
  }

Answer 2

SET PORT=8090 && nodemon server.js that worked for me

Answer 3

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.

Answer 4

automatically run this port :3000,I tried windows working react

"devDependencies": {
    "react-scripts": "0.8.4"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  }

Answer 5

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.

Answer 6

• 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.
