[Bug] Error: An `executablePath` or `channel` must be specified for `puppeteer-core`

Describe the bug

1. Fresh installation with : npm install puppeteer puppeteer-extra puppeteer-extra-plugin-stealth

2. Copy paste the main from puppeteer-extra-plugin-stealth npm

3. Start the program with node index.js

4. I get the error Error: An 'executablePath' or 'channel' must be specified for 'puppeteer-core':

Code Snippet

// puppeteer-extra is a drop-in replacement for puppeteer,
// it augments the installed puppeteer with plugin functionality
const puppeteer = require('puppeteer-extra');

// add stealth plugin and use defaults (all evasion techniques)
const StealthPlugin = require('puppeteer-extra-plugin-stealth');
puppeteer.use(StealthPlugin());

// puppeteer usage as normal
puppeteer.launch({ headless: true }).then(async browser => {
  console.log('Running tests..')
  const page = await browser.newPage()
  await page.goto('https://bot.sannysoft.com')
  await page.waitForTimeout(5000)
  await page.screenshot({ path: 'testresult.png', fullPage: true })
  await browser.close()
  console.log(`All done, check the screenshot. ✨`)
});

=================================== Edit So it seems that puppeteer-core require now the executablePath as mandatory? I think this is new I never got this error before.

I fixed it by adding the path to the chrome.exe file:

const os = require("os");
// puppeteer-extra is a drop-in replacement for puppeteer,
// it augments the installed puppeteer with plugin functionality
const puppeteer = require('puppeteer-extra');

// add stealth plugin and use defaults (all evasion techniques)
const StealthPlugin = require('puppeteer-extra-plugin-stealth');
puppeteer.use(StealthPlugin());

// puppeteer usage as normal
puppeteer.launch({ headless: true, executablePath: `${os.homedir()}/.cache/puppeteer/chrome/win64-1045629/chrome-win/chrome.exe`}).then(async browser => {
  console.log('Running tests..')
  const page = await browser.newPage()
  await page.goto('https://bot.sannysoft.com')
  await page.waitForTimeout(5000)
  await page.screenshot({ path: 'testresult.png', fullPage: true })
  await browser.close()
  console.log(`All done, check the screenshot. ✨`)
});

Maybe puppeteer-extra could look for the presence of a browser in the cache and automatically find the installed one ? Probably linked with #728

Thanks @bribes, this worked for me:

import { executablePath } from 'puppeteer';
import puppeteer from 'puppeteer-extra';

  const browser = await puppeteer.launch({
    headless: true,
    executablePath: executablePath(),
  });

Same here

Edit:

Solutions:

• Setting executablePath: require('puppeteer').executablePath().
