I think the issue may be due to the Tailwind version. Version 4 does not use npx tailwindcss init. Please verify your Tailwind version and install it according to the Tailwind documentation.

Tailwind version 4 have new instructions, check this docs:

https://tailwindcss.com/docs/upgrade-guide
https://tailwindcss.com/docs/installation/using-vite

If you want use old method u have to use npm install -D tailwindcss@^3.4.17 postcss autoprefixer command

how to setup this purge from tailwind.config.js in v4?
purge: ['./index.html', './src/**/*.{vue,js,ts,jsx,tsx}'],

Purge happens "by default" in a way, so it shouldn't be neccessary most of the time. It seems like you might be using Vite? If so, you only need to explicitly state source paths if files that use Tailwind classes are not in Vite's module graph.
