Introduction

If you're working on a Django project and have integrated Playwright for browser automation, you might run into a frustrating error when running your Docker setup. The error message indicates a version mismatch between the installed Playwright package and the Chromium browser version. This guide will help you resolve this issue effectively.

The Problem

When you run the command:

and subsequently use a function that depends on Playwright, you might encounter an error like this:

This indicates that Playwright is looking for Chromium version 1067, but you have version 1071 installed in your Docker environment. This version discrepancy can lead to runtime failures and can be a major hindrance while developing your application.

Understanding the Error

Why Does This Happen?

The primary reason behind this mismatch is that you may have installed Playwright and Chromium at different times or with different commands, which could lead to discrepancies in browser versions.

Solution Overview

To resolve this issue, it’s best to let Playwright handle the installation of the browser and its versions. This will ensure that the versions are compatible with the installed Playwright package.

Updated Dockerfile

Here’s an updated approach you can take by modifying your existing Dockerfile:

Key Changes Made

Removed playwright install-deps chromium: Playwright will automatically manage its dependencies when you run playwright install.

Reorganized installation commands: Ensured that Playwright installs Chrome/Chromium in alignment with its version.

Important Note

Whenever you upgrade Playwright in the future, run the command:

This is crucial to ensure that Playwright installs compatible versions of the browsers.

Conclusion

By allowing Playwright to manage its own browser installations, you not only simplify your Docker setup but also prevent potential version mismatches which can lead to runtime errors.

Make sure to always check for any updates in Playwright’s documentation or release notes whenever you make changes to your installation, ensuring smooth operations for your Django project.
