While running crawl4ai on my home PC, I found that the required Playwright browser revision was missing. Installing the latest Playwright still did not include this exact revision.

1
BrowserType.launch: Executable doesn't exist at C:\Users\Evepupil\AppData\Local\ms-playwright\chromium-1187\chrome-win\chrome.exe

After trying multiple versions, I found that:

1
npm install @playwright/test@1.55.0

This version includes the exact Chromium 1187 browser build.

After installing that Playwright version, install the matching Chromium with:

1
npx playwright install chromium
