Looking at your error, it seems like there’s a corrupted import in your vite.config.js file. The error shows repeated @tailwindcss text which suggests the file got mangled somehow.

Here’s how to fix it:

Fix your vite.config.js

Replace your current vite.config.js with this clean version:

import { defineConfig } from 'vite' import react from '@vitejs/plugin-react' import tailwindcss from '@tailwindcss/vite' // https://vite.dev/config/ export default defineConfig({ plugins: [ react(), tailwindcss(), ], })

Install the correct Tailwind CSS package

Make sure you have the right Tailwind CSS Vite plugin installed:

npm install -D @tailwindcss/vite

Alternative approach

If you’re still having issues, you can use the traditional Tailwind setup instead:

Install Tailwind the standard way:

npm install -D tailwindcss postcss autoprefixer npx tailwindcss init -p

Update your vite.config.js to:

import { defineConfig } from 'vite' import react from '@vitejs/plugin-react' export default defineConfig({ plugins: [react()], })

Add Tailwind directives to your CSS file:

@tailwind base; @tailwind components; @tailwind utilities;

The corrupted file is likely causing the module resolution issues you’re seeing.

If it not done, can I see the repo once to get the error that might be there?

{

"rewrites": [

{ "source": "/(.\*)", "destination": "/" }

]

} add vercel.json file in your project
