[v4] stuck at "[postcss] 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 have done exactly these steps and same result

Please consider providing a project that reproduces the unexpected behavior so we can help debug for you.

for me- literally opening a new react project in vs Code following the documentation exactly gives me the error every time.

Hey, I also faced the same issue.
I think you might have downloaded v4 instead of the previous one if not.

Try completely deleting the postcss.config file and try again.

Hope it helps.

I ran into the same issue when upgrading to Tailwind CSS v4. The problem appears if you're still trying to use tailwindcss directly as a PostCSS plugin, but in v4, that plugin logic now lives in a separate package.

How I fixed it:

1. Make sure you have PostCSS v8 installed:
2. Update and confirm these packages are installed at the versions shown (or newer):

“tailwind-merge”: “^3.0.1”,
“tailwindcss-animate”: “^1.0.7”,
“@tailwindcss/postcss”: “^4.0.5”,
“prettier-plugin-tailwindcss”: “^0.6.11”,
“tailwindcss”: “^4.0.5”,
“postcss”: “^8”

3. In your PostCSS configuration (e.g. postcss.config.js), make sure you require @tailwindcss/postcss instead of tailwindcss directly:

[postcss] It looks like you're trying to use tailwindcss directly as a PostCSS plugin. The PostCSS plugin has moved to a separate package...

// postcss.config.js
module.exports = {
  plugins: [
    require('@tailwindcss/postcss'),
    // other plugins...
  ],
}```

I did exactly this and double checked and still getting this error. ugh!
