Puppeteer Launch Issue: Chromium Revision Not Installed

Other Questions Puppeteer
1

I installed Puppeteer via npm but receive a ‘Chromium revision not downloaded’ error when running sample code. Below is a revised example:

const pBrowser = require('puppeteer');
(async function initiateSession() {
  const engine = await pBrowser.launch();
  const newTab = await engine.newPage();
  await newTab.goto('https://example.org');
  await newTab.screenshot({ path: 'screenshot_capture.png' });
  await engine.close();
})();

Please advise on resolving this problem.

The error typically indicates that Puppeteer couldn’t complete the Chromium download during the installation process. In my experience, this is often due to network restrictions or permission issues within the environment. Resolving the issue involved checking if any proxy or firewall settings interfered with the download. I also found that manually downloading the specific Chromium revision or clearing npm cache before reinstalling occasionally resolves the problem. It might be useful to adjust your npm configuration to ensure proper access and verify that your system meets all environmental prerequisites.
