My code is as follows:

 const browser = await puppeteer.launch({headless: params["headless"]});

 
    const page = await browser.newPage();
    await page.setJavaScriptEnabled(true);
    await page.setRequestInterception(true);
...

The issue is that I am unable to run it. I am getting following exception.

(node:7008) UnhandledPromiseRejectionWarning: Error: Could not find browser revision 756035. Run "npm install" or "yarn install" to download a browser binary.

How do I fix it ? It was working just fine before.

puppeteer node.js

If anyone else is facing similar issue then delete node modules folder and run again. It will work

No need to delete all node_modules folder

Run npm i puppeteer and it will update your revision of chromium

If any of the above solutions don't work, in my case (running on ubuntu 16.04.3 LTS on a digitalocean droplet) this error was caused because npm refused to install chromium as a dependency of puppeteer. I don't know the cause of this behavior, but I've seen it reported elsewhere. I'm using the full version of puppeteer, not puppeteer-core.

What worked for me was to manually install chromium via npm:

npm install chromium

And then in my puppeteer script, explicitly set the executable:

puppeteer.launch({
  executablePath: './node_modules/chromium/lib/chromium/chrome-linux/chrome',
  // be sure to verify that this path matches your installation, but this is where npm put it in my node_modules directory
  // and of course include any other launch arguments you need here
});

But I'd sure love to know if there's a better solution than this.

For future references, I had to do the following to make it work on my ubuntu server (launching Chrome):

  1. Point to your local chromium (launch option - executablePath, in my case : node_modules/puppeteer/.local-chromium/linux-809590/chrome-linux/chrome')

  2. Update your packages :

sudo apt-get install libpangocairo-1.0-0 libx11-xcb1 libxcomposite1 libxcursor1 libxdamage1 libxi6 libxtst6 libnss3 libcups2 libxss1 libxrandr2 libgconf2-4 libasound2 libatk1.0-0 libgtk-3-0

  1. Add that sneaky package :

sudo apt-get install -y libgbm-dev
