migrating problem to v4 tailwindcss; postcss error

[llaamma]

when I run my code although I upgraded my code to v4, according to the docs, it always says:
ERROR Cannot start nuxt: It looks like you're trying to use tailwindcss directly as a PostCSS plugin. The PostCSS plugin has moved to a separate package, so to continue using Tailwind CSS with PostCSS you'll need to install @tailwindcss/postcss and update your PostCSS configuration.
I'm using Nuxt and TypeScript. Maybe somebody can help me please!

Consider providing a remotely-hosted git repository that reproduces the unexpected behavior.

Keep in mind that you can't use both @nuxt/ui and shadcn-nuxt together.

If you have both installed, remove @nuxt/ui from your dependencies (using npm, yarn, or any other package manager) and also remove its mention from the modules section in nuxt.config.ts.
