Describe the bug

In a newly created Nuxt.js project, running nuxt dev fails after adding @nuxtjs/tailwindcss to nuxt.config.ts. The error points to this line of code.

Here is my nuxt.config.ts

export default defineNuxtConfig({
  devtools: { enabled: true },
  modules: ['@nuxtjs/tailwindcss'],
});

Additional context

The project is a pnpm monorepo where all packages are inside the folder apps and @nuxtjs/tailwindcss has been installed with pnpm --filter=@project/nuxtjs -D -E @nuxtjs/tailwindcss
