[Bug]: Playwright error — Host system is missing dependencies to run browsers

[dtinth]

Current Behavior (bug)
When running a Playwright test, browsers won’t run at all. Instead, tests immediately fail with this error message:

Running 2 tests using 1 worker
  1) [chromium] › example.spec.js:4:1 › has title ──────────────────────────────────────────────────

Expected Behavior (fix)
Browsers should run just like in most environments.

I'm also trying to get Playwright to run in Devbox.

Relevant Nix packages seem to be playwright-test and playwright-driver. There are instructions here for getting Playwright to work in NixOS, but it's unclear how to translate that across to Devbox. Searching for playwright-driver.browsers gives no results at both https://www.nixhub.io/ and https://search.nixos.org/packages so I don't know how to install that package and obtain a value for PLAYWRIGHT_BROWSERS_PATH.

The following devbox.json let me run playwright cr in a devbox shell and started up chromium:

{
  "packages": [
    "playwright@latest",
    "playwright-driver@latest"
  ],
  "shell": {
    "init_hook": "export PLAYWRIGHT_BROWSERS_PATH=$(nix build --print-out-paths nixpkgs#playwright-driver.browsers)"
  }
}

Additionally, playwright-test just works, it does the above export for you

I met the Missing libraries error in the Github CI. I was adding devbox to the existing setup. Playwright was installed via pnpm.

For me the solution was PLAYWRIGHT_SKIP_VALIDATE_HOST_REQUIREMENTS=true. Playwright started to work again after adding this env var.
