vuetify-loader 1.6 is incompatible with laravel mix, vue-loader 15 currently does not support vue rules with oneOf

I'm trying to install the vue on the laravel. I believe I got it, but when I run the npm run watch or npm run dev, it generates this error. I've tried several things and I can't solve

Error: [VueLoaderPlugin Error] vue-loader 15 currently does not support vue rules with oneOf.

File: webpack.mix.js

const mix = require('laravel-mix');

const VuetifyLoaderPlugin = require('vuetify-loader/lib/plugin');
var webpackConfig = {
        plugins: [
            new VuetifyLoaderPlugin()
            // other plugins ...
        ]
    // other webpack config ...

mix.webpackConfig(webpackConfig);

    .sass('resources/sass/app.scss', 'public/css');

Someone help me please

Right so you are using Vuetify this is because vuetify-loader 1.6 has some problems with laravel mix setup. More specifically it's because the order of vue-loader and vuetify-loader was added by laravel-mix.

For now you need to add VuetifyLoaderPlugin after laravel-mix compiles all the plugins.

So remove the new VuetifyLoaderPlugin() from var webpackConfig variable. And add new VuetifyLoaderPlugin() after every plugin is added.

mix.extend('vuetify', new class {
    webpackConfig (config) {
        config.plugins.push(new VuetifyLoaderPlugin())
    }
})
mix.vuetify()

If everything is overwhelming to you, I have a small library that does everything for you.

All you need to do is to install it

npm i vuetifyjs-mix-extension -D

require it

require('vuetifyjs-mix-extension')

use it

mix.js('resources/js/app.js', 'public/js').vuetify('vuetify-loader')

Those two approaches should do the same thing for you. You can choose on your preference.
