npm install puppeteer --ignore-scripts

 

the problem may be caused by your internet can't download the newest Chromium，so you can use
npm install puppeteer --ignore-scripts to skip download

and then，when you use the script ，you should set the executablePath like

const path = require('path'); // the browser path const path = path.resolve('C:\Program Files\Google\Chrome\Application\chrome.exe') const browser = await puppeteer.launch({ executablePath: path })
