Error: Failed to launch the browser process! spawn /app/node_modules/puppeteer/.local-chromium/linux-756035/chrome-linux/chrome ENOENT

Steps to reproduce

Tell us about your environment:

• Puppeteer version: ^3.3.0
• Platform / OS version: Ubuntu 20.04 LTS
• URLs (if applicable):
• Node.js version: 12.16.1

What steps will reproduce the problem?

I know there’s a lot of issues like this one, but I tried every solutions I saw, such as add args to the .launch, reinstall all required dependencies, reinstall puppeteer, reinstall Chromium, try Chrome… But I still get this error.

1. In backend : `const puppeteer = require(‘puppeteer’); const router = require(‘express’).Router();

router.get(‘/create’, async (req, res) => { console.log(“BEGINING PDF CREATION PROCESS”); try { // Starting browser and got to a new page const browser = await puppeteer.launch({ headless: true }); const page = await browser.newPage(); await page.goto(‘https://google.com’); // Define the media type await page.emulateMediaType(‘screen’); // Create PDF with custom options const buffer = await page.pdf({ format: ‘A4’, printBackground: true, preferCSSPageSize: true }); // Send PDF to front res.writeHead(200, { ‘Content-Type’: ‘application/pdf’, ‘Content-Length’: buffer.length }); res.end(buffer); // Close browser await browser.close() console.log(“ENDING PROCESS SUCCESSFULY”); } catch (error) { console.log(“ENDING PROCESS UNSUCCESSFULY”); console.log(error); } });

module.exports = router2. frontend :axios({ method: ‘get’, url:‘/pdf/create’ }) .then(res => { console.log(“Response received”) return res .arrayBuffer() .then(res => { const blob = new Blob([res], { type: ‘application/pdf’ }) saveAs(blob, ${order._id}.pdf) }) .catch(error => console.log(error)) })` 3.

What is the expected result? It should send the PDF buffer to the front.

What happens instead? I returns the error above.

@qiaochunmei 这解决了问题. 祝好运.

unzip node_modules/puppeteer/.local-chromium/chrome-mac.zip
cp -r chrome-mac/Chromium.app/ ./node_modules/puppeteer/.local-chromium/mac-756035/chrome-mac/Chromium.app/

The error I was getting was: spawn D:\Users\johns10\Documents\GitHub\userdocs_umbrella\apps\userdocs_web\assets\dist\win-unpacked\resources\app.asar\node_modules\puppeteer\.local-chromium\win64-856583\chrome-win\chrome.exe ENOENT

I solved it like this:

async function openBrowser() {
  if (isDev) {
    var executablePath = puppeteer.executablePath()
  } else {
    var executablePath = puppeteer.executablePath().replace("app.asar", "app.asar.unpacked")
  }
  const browser = await puppeteer.launch({ executablePath: executablePath });

  return browser
}
