GitHub Actions Linux fails to find module '../lightningcss.linux-x64-gnu.node' even though it works locally on mac

[Andrew-Chen-Wang]

Public reproduction: https://github.com/Andrew-Chen-Wang/template-nextjs

GitHub action: https://github.com/Andrew-Chen-Wang/template-nextjs/actions/runs/14348535357/job/40222977259

I've installed tailwind and vitest, and it seems like vite installed lightningcss. I'm on a mac (latest version, silicon), and running the production build command works fine. However, when running on Github actions on Linux, it fails.

Hey @Andrew-Chen-Wang, we have the same problem in Vercel. We set some optional dependencies to fix this issue.

tailwindlabs/tailwindcss#15806 (comment)

[Andrew-Chen-Wang]

Thanks! Dug through a little bit of the cause for the issue, and it seems to be a package manager issue. I wrote a comment in your linked comment

Folks are referencing an issue in npm/cli being a cause for npm users. It seems like a PR was merged, but the team just cut a release a few days ago, so I'd expect about a month before another release is cut. See PR npm/cli#8184

The optional dependencies are the ones that worked tho for now!

  "optionalDependencies": {
    "@tailwindcss/oxide-linux-arm64-musl": "^4.0.1",
    "@tailwindcss/oxide-linux-x64-musl": "^4.0.1",
    "lightningcss-linux-arm64-musl": "^1.29.1",
