Tailwind v4 not working (create-next-app@latest) on arch linux

[diamondAlex]

This is a long shot question, but when I use create-next-app@latest for a new project, the tailwindcss isn't compiled. Tailwind v4 doesn't work, but Tailwind v3 does.

Nextjs version : "15.2.3"
"tailwindcss": "^4",
"@tailwindcss/postcss": "^4",

Everything is set up correctly according to the tailwind documentation. It also works on all my other machines.

My question is, what could prevent tailwindcss from being compiled without giving any errors on a specific machine?

I had the same problem, the base tailwind styles and custom css it came with were there, but the classes weren't compiling.

I finally got it to work when I git init the project and deleted the .next folder and ran dev again.

really strange. It works for me as well

So weird. This also happened to me. Tried just deleting the .next folder but that did not work. I had to do the git init.

Works on newest versions.
