Thanks for reporting. This is curious, because all this gem does is package the upstream CLI binary executables.

Can you reproduce this when you use the upstream binary (without this gem's packaging)? You can download it from here: https://github.com/tailwindlabs/tailwindcss/releases/tag/v4.0.3

If you reproduce with that file, then we should report this upstream because it's likely an issue with the new bun tooling being used to precompile the tailwindcss CLI.

Possibly related: tailwindlabs/tailwindcss#15181

Closing this ticket, the upstream issue is almost definitely tailwindlabs/tailwindcss#15181

I've created an information issue for anybody who might want to report this in the future, explaining what we know and redirecting them to the upstream report.

Should be fixed in https://github.com/flavorjones/tailwindcss-ruby/releases/tag/v4.0.4
