Hi @Cordobes. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
It looks like you're encountering a PostCSS error related to Tailwind CSS in your Nuxt project. This error occurs when there's an issue with how PostCSS is processing your Tailwind CSS configuration.
Based on the knowledge sources, this could be related to a few issues:
1. There might be a compatibility issue between your PostCSS version and Tailwind CSS. Recent Nuxt versions have been updating their PostCSS dependencies, as seen in several pull requests (PostCSS 8.4.39 update and PostCSS 8.5.1 update).
2. The error specifically mentions "Unknown word 'use strict'" which suggests there might be an issue with how the JavaScript module is being processed by PostCSS.
Here are some potential solutions:
1. Check your PostCSS configuration
Make sure your PostCSS configuration in
nuxt.config.ts
is properly set up:
2. Fix local PostCSS plugins handling
This could be related to a known issue with handling local PostCSS plugins that was fixed in Nuxt. As mentioned in this PR, there was a regression with loading local PostCSS plugins.
3. Check package versions compatibility
Make sure your package versions are compatible. You might need to update or downgrade certain packages to ensure compatibility. The error suggests there might be an issue with how Tailwind CSS is being imported.
4. Try using the official Nuxt Tailwind module
Instead of manually configuring Tailwind, you might want to use the official Nuxt Tailwind module as recommended by a Nuxt team member:
Then add it to your modules in nuxt.config.ts
:
This module handles the integration between Nuxt and Tailwind CSS and might resolve your issue.
If you're using Tailwind v4, note that there have been some HMR issues reported with it in Nuxt, as mentioned in this GitHub issue.
Let me know if these suggestions help or if you need further assistance!

You're still encountering the same PostCSS error with Tailwind CSS in your Nuxt project. This error is specifically related to how PostCSS is trying to process the Tailwind CSS JavaScript file as CSS content.
Based on the knowledge sources, this issue could be related to:
1. Tailwind CSS v4 compatibility issues: There have been reported issues with Tailwind CSS v4 and Nuxt, particularly with HMR (Hot Module Replacement) when using server-side rendering, as mentioned in this GitHub issue.
2. PostCSS configuration issues: Recent changes in how Nuxt handles PostCSS plugins might be affecting your setup, as indicated by this PR which refactored how PostCSS configs are loaded.
Here are some potential solutions:
1. Use the official Nuxt Tailwind module
As recommended in the GitHub issue:
2. If you're using Tailwind v4, update your CSS imports
For Tailwind CSS v4, you need to use the new import syntax in your CSS file:
As shown in Nuxt UI documentation.
3. Temporarily disable SSR to test
As mentioned in the GitHub issue, setting
ssr: false
in your nuxt.config.ts
might fix the issue temporarily:
However, this is just a workaround and not a permanent solution if you need SSR.
4. Check for PostCSS plugin compatibility
Make sure your PostCSS plugins are compatible with your Nuxt version. Nuxt comes with several PostCSS plugins pre-configured as mentioned in the Nuxt documentation:
This issue might be resolved in newer versions of Nuxt or Nitro, as indicated by a comment in the GitHub issue that mentions a fix in a Nitro PR: "build status is synected to the server. on initial build and reloads there is no longer worker is not ready and cannot find path / errors!"
If you continue to face issues, consider updating to the latest versions of Nuxt and related packages, or temporarily downgrading Tailwind CSS to a version known to work well with your Nuxt setup.

now my UI is not loading š
----------------------
It looks like you're encountering an error when trying to start your Nuxt application. The error message indicates that Nuxt is trying to load a module called
ui-pro
but can't find it.
This error is related to the Nuxt UI Pro module, which is a premium component library built on top of Nuxt UI. Based on the error, it seems the module is referenced in your configuration but isn't properly installed.
Here's how to fix this issue:
1. Install the Nuxt UI Pro package
First, you need to install the @nuxt/ui-pro
package:
If you're using pnpm (which appears to be the case based on your error paths), make sure you have shamefully-hoist=true
in your .npmrc
file or install tailwindcss
in your project's root directory as mentioned in the Nuxt UI Pro installation documentation.
2. Update your nuxt.config.ts file
Make sure your nuxt.config.ts
file correctly references the module:
3. Set up your CSS file
Create or update your CSS file to import Tailwind CSS and Nuxt UI Pro:
4. Wrap your app with the App component
In your app.vue
file:
The error you're seeing is specifically related to module resolution, which was addressed in recent Nuxt updates as mentioned in this PR and this PR. These updates improved how Nuxt resolves module paths.
If you continue to face issues after following these steps, you might want to check if there's a typo in your module name in the nuxt.config.ts
file or if you're using a non-standard module path.
