While running the script throws cannot find module 'dotenv'

Question

While loading the .env file to pass env values to the getToken.js script in the cypress root folder throws Cannot find module 'dotenv'error. I have installed npm install dotenv. Could someone please advise what I am missing here ? .env file is available in cypress root folder.

Environment : Windows 10 > git bash /command prompt

    const puppeteer = require("puppeteer");
    require('dotenv').config({path: '.env'})
    
    const baseURL = process.env.CYPRESS_BASE_URL
    const testsUser = process.env.CYPRESS_TESTS_USERNAME
puppeteer
  .launch({ headless: true, chromeWebSecurity: false, args: ['--no-sandbox'] })
  .then(async browser => {
    const page = await browser.newPage();
    await page.goto(`${baseURL}/login`);

    await page.waitFor(2000);
    await page.waitForSelector("input[name=username]");
    await page.type("input[name=username]", testsUser , {
      delay: 50
    });

    browser.close();
  });

You should check if dotenv is installed, otherwise type in terminal:

npm install --save dotenv 

or dotenv-extended

npm install --save dotenv-extended
