To fix, you'll need to install the missing dependencies and the latest Chromium 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). Step 8 − While working on a test, we have to add the below Puppeteer library in the code.Jest args: -e2e -spec -max-workers=36Īt ChildProcess.spawn (internal/child_process.js:394:11) Step 7 − After the installation of Puppeteer and Puppeteer core, we shall find the node_modules folder and package.json file generated within the empty folder we created in Step 2. Step 6 − For installation of Puppeteer core, run the below mentioned command − Step 5 − For Puppeteer installation, run the below mentioned command − Step 4 − Open the terminal and move from the current directory to the directory of the empty folder that we have created in Step 2. The details on how to install VS Code is discussed in detail in the Chapter of VS Code Configuration.
Step 3 − Launch the Visual Studio Code application and click on the Open folder link and import the folder we have created in Step2. Step 2 − Create an empty folder, say puppeteer in a location. The details on how to install NodeJs is discussed in detail in the Chapter of Installation of NodeJS.
