After I upgraded "@nuxthub/core": "^0.5.14" to "^0.5.16" the following problem occurred about core

[dennisyang1986]

I have found that the "pnpm update" command should not be used, otherwise it will definitely cause this result.
only upgrading core to 0.5.16 won't be a problem.

@yangzhaokun — nuxt/ui#1665 should fix this warning message (which is included in the just released v2.16.0 of Nuxt UI).

I have found the source of the error, so as not to mislead others, I will write down the specific reasons here

When running npm run dev, this module will look for these files:
./assets/css/tailwind.css
./tailwind.config.{js,cjs,mjs,ts}
If these files don't exist, the module will automatically generate a basic configuration for them, so you don't have to create these files manually.
You can create the tailwind.config.js file by running the following command:
npx tailwindcss init

If you don't want to inject the CSS file, you can set cssPath to false , in nuxt.config.ts

export default defineNuxtConfig({
  tailwindcss: {
    cssPath: false,
  }
})
