TailwindCSS not working with Vite + React

Question

I am initializing TailWindCSS using https://tailwindcss.com/docs/guides/create-react-app on a Vite + React + JavaScript project but cant get it to work, It seems like postcss and autoprefixer is not getting installed, when I try to install manually it gives the following error

warning Pattern ["postcss@^8.4.20"] is trying to unpack in the same destination "C:\\Users\\NUR\\AppData\\Local\\Yarn\\Cache\\v6\\npm-postcss-8.4.20-64c52f509644cecad8567e949f4081d98349dc56-integrity\\node_modules\\postcss" as pattern ["postcss@^8.4.18","postcss@^8.4.20"]. This could result in non-deterministic behavior, skipping.

Answer 1

I followed the doc to install tailwind with Vite and React and it didn't work too.

Don't install packages manually, use the npx tailwindcss init -p but create manually the file postcss.config.cjs with:

module.exports = {
  plugins: {
    tailwindcss: {},
    autoprefixer: {}
  }
};

Don't forget the rest of the guide and it will work
