Playwright Browser Installation Issue ​

If Chromium is not installed on your system or the version is mismatched, you may see errors when running a test from the UI. A common error message is:

Before/After hook failed with message: browserType.launch: Executable doesn't exist at C:\Users\<user>\AppData\Local\ms-playwright\chromium-xxxx\chrome-win\chrome.exe

This means the expected version of Chromium was not found. The error can occur if the wrong version of Playwright is installed or if the browser binaries have not been downloaded.

How to Fix the Issue ​

  1. Open your project in VS Code.

  2. In the root project folder, open a terminal and run:

    bash
    npx playwright install

  3. (Optional) Check which version of Playwright is installed:

    bash
    npx playwright --version

  4. (Optional) Check which browser versions would be installed:

    bash
    npx playwright install --dry-run

  5. If the issue still persists, clear the cache and reinstall everything:

    bash
    rm -rf node_modules
rm -rf ~/.cache/ms-playwright
npm install
npx playwright install

  6. Make sure you're using the Playwright version expected by your project. For example, to install version 1.50.1:

    bash
    npm install playwright@1.50.1
npx playwright install
