GNU or rust related issue

After upgrading to v4, I started getting below error, the error happens only in CI but not in development. I have bundled the gem locally with a mac laptop running on ubuntu 24.0

How the Gemfile.lock looks like

    tailwindcss-rails (4.2.3)
      railties (>= 7.0.0)
      tailwindcss-ruby (~> 4.0)
    tailwindcss-ruby (4.1.7-arm64-darwin)
    tailwindcss-ruby (4.1.7-x86_64-darwin)
    tailwindcss-ruby (4.1.7-x86_64-linux-gnu)

The error on github CI

≈ tailwindcss v4.1.7

Sorry you're having a problem. Please report this upstream at tailwindlabs/tailwindcss.

This gem (tailwindcss-rails) uses another gem (tailwindcss-ruby) to install the upstream tailwindcss CLI. If there are issues with running that binary executable, they should be reported there. Thanks.
