[Vuejs]-Vue component library not working together with vuetify in nuxt js

Have you updated nuxt.config.js the way it says in the Vuetify documentation and the nuxtjs/vuetify plugin page?

// nuxt.config.js
{
  buildModules: [
    // Simple usage
    '@nuxtjs/vuetify',

    // With options
    ['@nuxtjs/vuetify', { /* module options */ }]
  ]
}
