Error: Unable to access unknown properties (reading 'extend')

Struggling to integrate the Vuetify library into my current Vue 3 project, encountering complications. An error message popped up post-compilation:

vuetify.js?ce5b:42021 Uncaught TypeError: Cannot read properties of undefined (reading 'extend') ...

Incorporating Vuetify in main.js:

import Vuetify from 'vuetify'
import 'vuetify/dist/vuetify.min.css'

const app = createApp(App)
app.use(Vuetify)
app.mount('#app')

All Vuetify imports align with official documentation. Could these issues be linked to my Vue project's version?

javascript vue.js vuetify.js vuejs3 vuetifyjs3

Answer №1

To integrate with Vue3, make sure to install vuetify@^3.0.1

Begin by importing it:

import 'vuetify/styles'
import { createVuetify } from 'vuetify'

Next, you need to create it:

const vuetify = createVuetify()

Finally, include it in your app:

app.use(vuetify)
