Puppeteer Error: Chromium revision is not downloaded

Question

I used npm i puppeteer as stated in the Documentation and I'm getting the following error:

(node:2066) UnhandledPromiseRejectionWarning: Error: Chromium revision is not downloaded. Run "npm install" or "yarn install" at Launcher.launch

when im trying this example (also from the docs):

const puppeteer = require('puppeteer');
(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await page.screenshot({path: 'example.png'});
  await browser.close();
})();

Also in the documentation:

Note: When you install Puppeteer, it downloads a recent version of Chromium (~170MB Mac, ~282MB Linux, ~280MB Win) that is guaranteed to work with the API.

Any help would be appreciated.

Solution 1

After many attempts I finally found the answer here:

sudo npm install puppeteer --unsafe-perm=true --allow-root

As @vsync pointed out, this only works for linux

Solution 2

I only managed to fix the issue by manually installing Chromium after much searching and trying most of the suggestions:

node node_modules/puppeteer/install.js

Solution 3

By default, the puppeteer module will run its install script (node install.js). However, in my case, I enabled ignore-scripts=true in my ~/.npmrc file, so it was never executed.

In that case, you have to run the command yourself:

node node_modules/puppeteer/install.js

To check: node_modules/puppeteer/.local-chromium/linux-<your_chrome_version>/ should exist now.

Solution 4

for linux:

1- you must have installed chromium browser using this command :

$sudo apt install -y chromium-browser

2- you have to get the excutable path of chromium using this command :

$which chromium-browser

3-put the executable path as an argument to the launch function :

   const puppeteer = require('puppeteer-core');
   (async () => {
   const browser = await puppeteer.launch({
   executablePath: '/usr/bin/chromium-browser',
   headless: false
    });
    const page = await browser.newPage();
    await page.goto('https://google.com');
    await page.screenshot({path: 'example.png'});

    await browser.close();
    })();

Solution 5

Confirming solutions presented here almost work. Here's my setup. Ubuntu 16.

Install chromium browser from command line then:

    const browser = await puppeteer.launch({
        executablePath: "/usr/bin/chromium-browser",
        args: ['--no-sandbox']
    });

This answer is specifically for linux, which makes it useless for many developers, because windows OS is still very dominant

[Anastasios Moraitis]

But ubuntu bash for windows is what will make it usefull

[Moses Schwartz]

@tramada Still Linux ;)

This was very helpful. Finally had some progress after reading this!

This solution fixed my problem. Thanks!

If the folder exist you can check the path, and files, or you can rename it and do the steps.

My local modules had puppeteer-core instead of puppeteer but the solution worked the same.

npm v7 does not have --unsafe-perm or equivalent anymore github.com/npm/feedback/discussions/121
