`@tailwindcss/vite` incompatible with Vite 8 dependency

[stipe-s]

Describe the bug

When installing @tailwindcss/vite in a project using Vite 8, npm fails to resolve the dependency tree because the plugin only supports Vite versions ^5.2.0 || ^6 || ^7.

Error message

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree

Found: vite@8.0.0
node_modules/vite
dev vite@"^8.0.0" from the root project

Could not resolve dependency:
peer vite@"^5.2.0 || ^6 || ^7" from @tailwindcss/vite@4.2.1
node_modules/@tailwindcss/vite

Steps to reproduce

1. Create a new project with Vite

npm create vite@latest

2. Select React (TypeScript variant)

3. Install Tailwind Vite plugin

npm install @tailwindcss/vite

4. npm throws a dependency resolution error.

Expected behavior

@tailwindcss/vite should either:

• support Vite 8, or
• clearly warn users that the plugin currently only supports Vite ≤ 7.

Environment

• Node: (your node version)
• npm: (your npm version)
• Vite: 8.0.0
• @tailwindcss/vite: 4.2.1
• OS: Windows
