Describe your issue

When downloading and running the tailwindcss-linux-x64-musl I get the bun CLI and not tailwind. The bug is not present with tailwindcss-linux-arm64-musl though. See the reproduction for a minimal setup.

This could be a Bun bug, since they are using Bun's https://bun.sh/docs/bundler/executables to create the executable.

This is super strange. I tested that exact reproduction in two separate host environments:

• macOS ARM64 + OrbStack (emulating an x64 container)
• Windows x86_64 + Docker Desktop (so no arch emulation)

Both of these produce the tailwindcss help output. I would've expected to not see it if that reproduction does not work for you. This makes me think its definitely a Bun bug but I'm not quite sure what's causing things to break or how.

What's your host OS and architecture?

I am using an Apple M1 with colima.

@IxDay I was able to reproduce this issue but only when using colima, using Docker or OrbStack seems to work just fine. This is bizarre... I guess we'll have to file a bug report with bun about this. Thanks for the repro!

Created an upstream bug report, maybe the folks over at Bun have some idea: oven-sh/bun#19536

@IxDay Sorry for asking something not related to the issue itself: does the watch command work in Docker for you?
