getting these errors for many nuxt ui pro components. I followed the migration steps outlined here: https://ui.nuxt.com/getting-started/migration but I still keep getting the errors. I upgraded tailwind, installed "@nuxt/ui-pro": "^3.0.2", and updated all files as shown in the migration doc.

Hi @erztemplerobba. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the errors you're encountering after migrating from Nuxt UI Pro v1 to v3, it appears you're facing issues with component template compilation. The error "Cannot read properties of undefined (reading 'theme')" suggests there might be missing configuration for the UI Pro components. Let me help you resolve this issue: Missing Configuration for UI Pro Components The migration from v1 to v3 of Nuxt UI Pro involves several key changes in how components are configured. The errors you're seeing likely stem from incomplete migration steps. 1. Ensure Proper CSS Import Make sure you've properly imported both Tailwind CSS and Nuxt UI Pro in your CSS file:
@import "tailwindcss";
@import "@nuxt/ui-pro";
@import "tailwindcss";
@import "@nuxt/ui-pro";
And make sure this CSS file is imported in your Nuxt config:
export default defineNuxtConfig({
modules: ['@nuxt/ui-pro'],
css: ['~/assets/css/main.css']
})
export default defineNuxtConfig({
modules: ['@nuxt/ui-pro'],
css: ['~/assets/css/main.css']
})
2. Update App Configuration In Nuxt UI Pro v3, the theming system has changed significantly. You need to update your app.config.ts file to use the new structure:
export default defineAppConfig({
ui: {
colors: {
primary: 'green',
neutral: 'slate'
}
},
uiPro: {
// Component-specific configurations go here
// For example:
banner: {
// Banner component configuration
},
blogPosts: {
// BlogPosts component configuration
}
// Other components...
}
})
export default defineAppConfig({
ui: {
colors: {
primary: 'green',
neutral: 'slate'
}
},
uiPro: {
// Component-specific configurations go here
// For example:
banner: {
// Banner component configuration
},
blogPosts: {
// BlogPosts component configuration
}
// Other components...
}
})
The key change is that UI Pro component configurations now go under the uiPro key rather than the ui key as in v1 Content Nuxt Blog. 3. Wrap Your App with UApp Component Ensure you've wrapped your app with the UApp component:
<template>
<UApp>
<NuxtPage />
</UApp>
</template>
<template>
<UApp>
<NuxtPage />
</UApp>
</template>
This component provides global configurations and is required for components like Toast and Tooltip to work properly Nuxt UI Pro Installation. 4. Check Component-Specific Theme Configurations For components like Banner and BlogPost that are giving errors, you might need to provide their specific theme configurations. For example:
export default defineAppConfig({
uiPro: {
banner: {
slots: {
root: [
'relative z-50 w-full',
'transition-colors'
],
// other slots...
},
variants: {
// variants configuration
}
},
// other components...
}
})
export default defineAppConfig({
uiPro: {
banner: {
slots: {
root: [
'relative z-50 w-full',
'transition-colors'
],
// other slots...
},
variants: {
// variants configuration
}
},
// other components...
}
})
You can find the specific theme configurations for each component in the UI Pro documentation under the "Theme" section for each component Banner Theme. 5. Remove Old Tailwind Config If you haven't already, remove your old tailwind.config.ts file and use CSS-first theming with the @theme directive in your CSS file as mentioned in the migration guide Content Nuxt Blog. If you continue to face issues after implementing these changes, you might want to check the specific components that are failing and look at their documentation for any special configuration requirements. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Error: Cannot find module '#build/ui-pro/footer-columns' imported from 'path/node_modules/@nuxt/ui-pro/dist/runtime/components/FooterColumns.vue'. I get these errors for each component that throws an error but the files exist.

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the error message you're encountering, it appears that there's an issue with the module resolution for Nuxt UI Pro components. The error Cannot find module '#build/ui-pro/footer-columns' suggests that the build process isn't correctly generating or locating the component files. This is a common issue when migrating from Nuxt UI Pro v1 to v3. Let me help you resolve this: Resolving the Module Resolution Error 1. Update Your Installation Method Make sure you've properly installed Nuxt UI Pro v3 as a module rather than a layer:
// nuxt.config.ts
export default defineNuxtConfig({
modules: ['@nuxt/ui-pro'],
css: ['~/assets/css/main.css']
})
// nuxt.config.ts
export default defineNuxtConfig({
modules: ['@nuxt/ui-pro'],
css: ['~/assets/css/main.css']
})
This is different from v1 where it was used as a layer with extends: ['@nuxt/ui-pro'] Nuxt UI Pro Installation. 2. Clear Nuxt Cache and Rebuild The error might be related to cached build files. Try clearing the Nuxt cache and rebuilding:
npx nuxi cleanup
# or manually delete the .nuxt, .output, and node_modules/.vite directories
npm install
npm run dev
npx nuxi cleanup
# or manually delete the .nuxt, .output, and node_modules/.vite directories
npm install
npm run dev
3. Check CSS Import Order Ensure your CSS imports are in the correct order:
@import "tailwindcss";
@import "@nuxt/ui-pro";
@import "tailwindcss";
@import "@nuxt/ui-pro";
And make sure this CSS file is properly imported in your Nuxt config. 4. Verify Component Usage For the FooterColumns component specifically, make sure you're using it correctly:
<template>
<UFooter>
<template #top>
<UContainer>
<UFooterColumns :columns="columns" />
</UContainer>
</template>
</UFooter>
</template>
<template>
<UFooter>
<template #top>
<UContainer>
<UFooterColumns :columns="columns" />
</UContainer>
</template>
</UFooter>
</template>
The FooterColumns component is designed to be used within the Footer component FooterColumns Usage. 5. Check for Theme Configuration Ensure you have the proper theme configuration for the FooterColumns component in your app.config.ts:
export default defineAppConfig({
uiPro: {
footerColumns: {
slots: {
root: 'xl:grid xl:grid-cols-3 xl:gap-8',
left: 'mb-10 xl:mb-0',
// other slots...
},
variants: {
active: {
// variants configuration
}
}
}
}
})
export default defineAppConfig({
uiPro: {
footerColumns: {
slots: {
root: 'xl:grid xl:grid-cols-3 xl:gap-8',
left: 'mb-10 xl:mb-0',
// other slots...
},
variants: {
active: {
// variants configuration
}
}
}
}
})
You can find the specific theme configuration in the UI Pro documentation FooterColumns Theme. 6. Check for Dependency Hoisting Issues If you're using pnpm, ensure that you've set shamefully-hoist=true in your .npmrc file or installed tailwindcss in your project's root directory as mentioned in the installation guide Nuxt UI Pro Installation. If you continue to face issues after implementing these changes, you might want to try creating a fresh project using one of the official Nuxt UI Pro templates as a reference:
npx nuxi init -t github:nuxt-ui-pro/starter my-starter
npx nuxi init -t github:nuxt-ui-pro/starter my-starter
This can help you identify any configuration differences between your project and a working example. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai is it necessary to have nuxt 4's /app/ structure or can I use the old nuxt 3 folder structure without /app ?
kapa.ai
kapa.ai5d ago
Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the knowledge sources, you can continue using the old Nuxt 3 folder structure without the /app/ directory in Nuxt 4. This is explicitly supported through backward compatibility. According to the Nuxt upgrade guide:
Nuxt now defaults to a new directory structure, with backwards compatibility (so if Nuxt detects you are using the old structure, such as with a top-level pages/ directory, this new structure will not apply).
Nuxt Upgrade Guide The migration to the new directory structure is not required:
However, migration is not required. If you wish to keep your current folder structure, Nuxt should auto-detect it. (If it does not, please raise an issue.)
Nuxt Upgrade Guide If you want to explicitly force the use of the Nuxt 3 folder structure in Nuxt 4, you can add this configuration to your nuxt.config.ts:
export default defineNuxtConfig({
// This reverts the new srcDir default from `app` back to your root directory
srcDir: '.',
// This specifies the directory prefix for `app/router.options.ts` and `app/spa-loading-template.html`
dir: {
app: 'app'
}
})
export default defineNuxtConfig({
// This reverts the new srcDir default from `app` back to your root directory
srcDir: '.',
// This specifies the directory prefix for `app/router.options.ts` and `app/spa-loading-template.html`
dir: {
app: 'app'
}
})
The main reason for the new directory structure in Nuxt 4 is for performance and IDE type-safety benefits, but using the old structure will continue to work fine. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Let me check the knowledge base for you again. One moment! :books: ---------------------- I understand you're still facing the module resolution error with Nuxt UI Pro components. Let's focus specifically on resolving this #build/ui-pro/footer-columns error. Based on the knowledge sources, this appears to be related to how Nuxt UI Pro v3 is structured and built. Let me provide some more targeted solutions: 1. Check if you're using the correct Vite plugin For Nuxt UI Pro v3, there's a specific Vite plugin that needs to be configured. The error suggests that the build process isn't correctly generating the theme files.
// vite.config.ts
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import uiPro from '@nuxt/ui-pro/vite'

export default defineConfig({
plugins: [
vue(),
uiPro({
uiPro: {
// Your theme configurations
}
})
]
})
// vite.config.ts
import { defineConfig } from 'vite'
import vue from '@vitejs/plugin-vue'
import uiPro from '@nuxt/ui-pro/vite'

export default defineConfig({
plugins: [
vue(),
uiPro({
uiPro: {
// Your theme configurations
}
})
]
})
This is different from the regular Nuxt UI plugin and is specifically required for UI Pro components UI Pro Theme Configuration. 2. Try a fresh node_modules installation Sometimes, dependency issues can cause these types of errors:
# Remove node_modules and reinstall
rm -rf node_modules
rm -rf .nuxt
npm install
# or yarn install, pnpm install, etc.
# Remove node_modules and reinstall
rm -rf node_modules
rm -rf .nuxt
npm install
# or yarn install, pnpm install, etc.
3. Check your Nuxt version compatibility Make sure you're using a compatible version of Nuxt with Nuxt UI Pro v3. Nuxt UI Pro v3 is designed to work with Nuxt 3, not Nuxt 4 (if you've upgraded). 4. Try using one of the official templates as reference The Nuxt UI Pro team provides official templates that are known to work correctly:
npx nuxi init -t github:nuxt-ui-pro/starter my-starter
npx nuxi init -t github:nuxt-ui-pro/starter my-starter
You can compare your configuration with this working example Nuxt UI Pro Installation. 5. Check for pnpm hoisting issues If you're using pnpm, ensure you've set shamefully-hoist=true in your .npmrc file or installed tailwindcss in your project's root directory:
# .npmrc
shamefully-hoist=true
# .npmrc
shamefully-hoist=true
This is specifically mentioned in the installation guide Nuxt UI Pro Installation. 6. Verify your license configuration Nuxt UI Pro requires a valid license. Make sure you've configured it correctly:
// nuxt.config.ts
export default defineNuxtConfig({
modules: ['@nuxt/ui-pro'],
css: ['~/assets/css/main.css'],
uiPro: {
license: process.env.NUXT_UI_PRO_LICENSE
}
})
// nuxt.config.ts
export default defineNuxtConfig({
modules: ['@nuxt/ui-pro'],
css: ['~/assets/css/main.css'],
uiPro: {
license: process.env.NUXT_UI_PRO_LICENSE
}
})
And ensure the environment variable is set Nuxt UI Pro Options. If you continue to face issues after trying these solutions, it might be worth creating a minimal reproduction of the issue and reaching out to the Nuxt UI Pro team through their GitHub repository or Discord channel. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
