[Vuejs]-How to use vuetify a-la-carte with laravel-mix?

So i assume you have did npm run production but your voyager.js not minified?

Afaik in mix, Minification will only take place during production builds (npm run production).

Is it possible that you are still importing the main library from Vuetify in your voyager.js file?
Like this:

import Vuetify from 'vuetify';

If you want to use the LoaderPlugin you have to make sure that you import Vuetify from the lib folder as follows:

import Vuetify from 'vuetify/lib';

Note the /lib suffix.
