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.

If you have chrome-linux.zip by chance here is instruction to get it into work

1. PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=1 yarn add puppeteer
2. make a folder named .local-chromium in node_modules/puppeteer
3. if you are in linux make another folder named linux-901912 in .local-chromium

version is the same as the version which you've downloaded chromimum e.g. in https://storage.googleapis.com/chromium-browser-snapshots/Linux_x64/901912/chrome-linux.zip
