v4 not building in x86_64 container built on arm64 mac #499

I'm not sure where to post this because I cannot tell if it's kamal, tailwindcss-ruby, or tailwindcss-rails that's the underlying issue. When running Inspecting the image I can confirm the file is present but I've not been able to make progress to understand what's failing or find anyone with a similar issue. Interestingly the build is completing when I run Finally, I'd like to thank y'all for the time you've spent integrating Tailwind into Rails. I've been using Tailwind since v2 and these latest gems and install have been the best to work with yet. Thank you and keep up the great work. |

@BaylorRae most likely your application's tailwind configuration is referencing a tailwind plugin that requires installation via npm (or another javascript package manager). I can't be sure or help more without additional information.

Hello, I have the same error run locally Any suggestions? |

@dmarczal Try running
Grab the executable path and run it with Reassemble the command from those arguments, does it run or does it emit a more verbose error than you're getting above? |

@stage-rl @dmarczal @BaylorRae If someone can help me reproduce what you're seeing, I would be happy to investigate further. To date I have not been able to guess at the combination of factors causing this. Please provide more information (or a project repository) to help me reproduce it! 🙏 |

As I said, locally it's also OK on my computer. But see the failed workflow: https://github.com/stage-rl/efectfit/actions/runs/13248836256/job/36981687456 |

I see the failed workflow. Unfortunately, that doesn't help me reproduce it so I can debug it, though. I'd like to ask the folks who've posted on this issue to help me reproduce it locally so I don't have to guess at the preconditions that trigger whatever is going on. |

Hm, I don't know how to help. OK, thanks a lot for the effort. Hopefully someone else will be more knowledgeable than myself |

This is my setup as well. I'll go back through the thread more closely when I'm back at my computer, but skimming through the comments we are seeing the same things. I'm on a M1 chip I believe and can run To fix my issue I ended up uninstalling the tailwindcss-rails gem, adding node to my dockerfile, and manually compiling the css into my I can't remember for certain, but I think when started a vanilla ruby-slim container that I was able to install the tailwindcss gem and have it work when I ran it by hand. It seems like it was at the asset pipeline level in rails that was causing issues. I wish I could be certain but I tried several different combinations of node/no-node etc.. It might be propshaft but I didn't take the time to try everything against sprockets. |

I don't have a mac, so I can't reproduce this. I need someone's further help to determine if the problem is with this gem, or with the upstream binary running in docker (and I'm quite sure it's the latter, but before opening a bug report upstream we need to positively determine this). As I asked a few days ago in #497 (comment) ... Try running

Like, just as a reminder, this gem (tailwindcss-rails) mostly provides view templates and rails-compatible config files. The tailwindcss-ruby gem just packages up the upstream binary executable. Problems like what's reported here are not likely to be caused by or under the control of either of the Ruby gems, which is why I keep asking people on this thread and other reports to run the binary executable directly to determine if it works and validate my hypothesis that this is a problem with the upstream binary. |

I am trying to get someone to provide a repro that can be reported upstream. To do that we need to run the binary executable directly on a directory/file structure that is reproducible by upstream tailwind maintainers who likely know nothing about ruby or rails. |

This is great, thank you for following this through to the end, @jtarchie. This demonstrates to me that the binary executable is behaving strangely in an x86_64 docker container that is built on an arm64 darwin host. Do you agree, does that fully describe the preconditions? If so am willing to attempt to report this upstream, though I would prefer if a Mac user reported it instead in order to help debug/diagnose with upstream maintainers. |

Side note, anyone kamal-deploying to x86_64 production platforms but developing on an arm64 platform should consider setting up a remote builder: https://kamal-deploy.org/docs/configuration/builder-examples/ |
