  • .vue()を追記すればOK
const mix = require('laravel-mix');

 | Mix Asset Management
 | Mix provides a clean, fluent API for defining some Webpack build steps
 | for your Laravel application. By default, we are compiling the Sass
 | file for the application as well as bundling up all the JS files.

mix.js('resources/js/app.js', 'public/js').vue() // ⭐️ 追記
    .sass('resources/sass/app.scss', 'public/css');

Laravel Mix 6で仕様変更になったのが原因だった
