Failed to Compile Syntax Error - 1.16.2 and Tailwind 3

[MxD-js]

Hey All,

I get this error when I run npm run build

Creating an optimized production build...

🌼 daisyUI components 1.16.2  https://github.com/saadeghi/daisyui
  ✔︎ Including:  base, components, themes[22], utilities
  
Failed to compile.

Syntax error: postcss-custom-properties: <css input> Unknown word (1:1)
> 1 | var(--b1)/var(--tw-bg-opacity,1)
    | ^

I followed this tailwind guide to create a fresh react project,

https://tailwindcss.com/docs/guides/create-react-app

if I remove require("daisyui") from tailwind.config.js then running npm run build, the project builds just fine but breaks when I add daisyui in the plugins section

I think this is related to a question I just asked ( #328 ) lol.
Tailwind 3 was just realeased and is the default when you start a new project. I think DaisyUI may need some changes to be compatible

@zenhorace @MxD-js Can you please provide an example github repo so I can reproduce this issue?
Because I just created a new project based on the Tailwind guide you mentioned and it works as expected.

Sure, here's the repo.

I cloned your sample project and get the same result, npm run start works fine, but npm run build throws error

worth noting that I am node v16.13.1 and npm 8.1.2

not sure this specifically has anything to do with tailwind 3 or DaisyUI specifically. It seems this issue is related to the postcss-custom-properties. They have an open issue for it. Apparently an issue with the parser and the workaround is to add a space so instead of var(--b1)/var(--tw-bg-opacity,1) we'd have var(--b1) / var(--tw-bg-opacity,1) which should get recognized by the parser. that would mean updating the line in src/base/colors.css

I don't get why it's flaring up just now with tailwind 3 though...

Can you please upgrade to latest version (1.16.4) and confirm that this fixes the issue?

negative, 1.16.4 does not fix it, although I am not noticing the space like mentioned by @zenhorace

[digitaltim-de]

Upgrade to 1.16.4 doesn`t fix it for me too.

[saadeghi]

Fixed in latest version 1.16.5
Thanks @zenhorace

[zenhorace]

Thanks for being so prompt with this fix! Ordinarily I'd try to suggest a fix myself but I'm traveling.
Anyhow, you're doing great work with this library and I'll look for opportunities to contribute in the future! 🙂

[MxD-js]

Yep, confirmed working 1.16.5, thanks @saadeghi and @zenhorace

[digitaltim-de]

Thanks, confirmed works for me too.
