Unable to find module 'prompt-sync'

Shreyash Kashyap

I am trying to take under input in nodejs using prompt but it shows me the following error:

node:internal/modules/cjs/loader:998
  throw err;
  ^

Error: Cannot find module 'prompt-sync'
Require stack:

  code: 'MODULE_NOT_FOUND',
  requireStack: [ 'D:\\Code\\C++\\Concepts\\conditionals.js' ]
}

I have installed 'prompt-sync' using npm but the issue still persists. This is my code:

const prompt = require('prompt-sync')();
let num = prompt("Enter your age: ");
console.log(typeof num);

I have tried restarting my pc and updated nodejs to its latest version(currently 9.2.0).

Any kind of help will be appreciated.

Clean your installed node modules like so:

npm cache verify
rm -rf node_modules
rm package-lock.json
npm i

rm works if you are under linux or gitbash on Windows. If not delete the node_modules folder and the package.lock.json. (not the package.json)

When executing the npm i, take a look if error messages comes. Not all npm packages are combatiple with all node versions.

Controll in your package.json if the prompt-sync module is in the dependency section. If not reinstall it. You need to be inside your project folder when you install a module.
