I'm making Tic Tac Toe game in JavaScript needed prompt-sync to get user inputs. After I installed prompt-sync module using npm I was getting this error whenever I tried to run this file. Did a quick google search to find that it requires npm install -g to activate it globally. Despite doing this I'm still getting the same Error. If anyone could please tell what's going wrong here!

Error:

$ node main.js

Not sure if you still need it, but for anyone who does:

Try using npm install prompt-sync.

1.Make sure you have Node and NPM installed

2.Run npm install prompt-sync in the terminal

Use this instead in the mand prompt (I wrote it while in the same folder as the .js file but that might not be necessary)

npm i prompt-sync

Source: https://www.npmjs./package/prompt-sync

After you install the prompt package go to package.json and add "type": "module" right before the keywords, like this:

{
  "type": "module",
  "keywords": [],
  "author": "",
  "license": "ISC",
  "description": "",
  "dependencies": {
    "prompt-sync": "^4.2.0"
  }
}
