Reproduction

Reproduction not possible because stackbiltz does not use bun

Description

This is not a breaking bug, but i'm curious why this only happens when using Bun, because it works perfectly fine except for this.

This does not happen when only using @nuxtjs/tailwindcss.

When i run the development server with bun run dev everything works as normal (because it uses node to run it), but when i use bun run --bun dev errors like

 WARN

 WARN  warn - As of Tailwind CSS v2.2, lightBlue has been renamed to sky.

 WARN  warn - Update your configuration file to silence this warning.

I think the answer might be obvious, since we do not have many options: a problem with the handling of weak/strong references, or more generally Bun's garbage collector implementation. I don't know how to express this directly to Bun maintainers.

[thunfisch987]

Sorry, i don't know much about the implementations and so on, that's why i asked.
Should i leave this open?
I don't mind the warnings

[thunfisch987]

After reading the other issue i remembered that i tried to use delete as explained in tailwindlabs/tailwindcss#4690 (comment) but it did not change anything, so it really seems to be delete that's the problem.

[ghost]

Any fixes for this, since NuxtUI automatically imports tailwind?

[thunfisch987]

You have to track it under oven-sh/bun#6747, fixes for this have to be implemented in Bun

[pi0]

A workaround to get rid of it:

// https://github.com/nuxt/ui/issues/809
import { createRequire } from 'node:module'
const _require = createRequire(import.meta.url)
const defaultColors = _require('tailwindcss/colors.js')
delete defaultColors.lightBlue
delete defaultColors.warmGray
delete defaultColors.trueGray
delete defaultColors.coolGray
delete defaultColors.blueGray

(you can put it in nuxt.config or essentially any place before module)

/cc @benjamincanac it is also doable within module but sadly I could not setup a dev env for nuxt/ui feel free to do it simply importing this way would solve module too.

[benjamincanac]

@pi0 Thanks a lot for the fix! 😊

@thunfisch987 @pi0 @benjamincanac If you remove the ...colors from theme.extend.colors, it works properly.
theme:{ extend:{ colors:{ ...colors } } }
