The bundledĬhromium that Puppeteer installs is missing the necessary shared library Getting headless Chrome up and running in Docker can be tricky. Instructions below might be still helpful if you are building your own image. Starting from v16.0.0 we are shipping a Docker image via the In a Docker container until v3.0.x - see our historicalįor reference. 👋 We used Cirrus Ci to run our tests for Puppeteer To fix this, set jest -maxWorkers=2 in your test command. This is likely caused by Jest autodetecting the number of processes on theĮntire machine ( 36) rather than the number allowed to your container ( 2). Create a New Node.js ProjectĬreate a new folder for your project and go to the directory.Jest args: -e2e -spec -max-workers=36Īt ChildProcess.spawn (internal/child_process.js:394:11) Please check the official documentation to check your version compatibility.

In this tutorial, we will be guiding you step-by-step on how to download images (.jpg. 😰 Fret not! We can do this by using automation and save all images from a website to a folder IN ONE GO. Imagine if you’re downloading 100+ images from a website manually, that’s a dreadful task. That’s only true if you’re only downloading a few images. Why use Puppeteer to download images?
