Please run Mix again in Laravel with Vuejs

 

Below code will solve this issue.

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

mix.browserSync({
    proxy: process.env.APP_URL,
    files: [
        'public/assets/css/**/*.css',
        'public/assets/js/bundle.js',
        'app/**/*.php',
        'resources/views/**/*.php',
    ]
})
.js('resources/assets/js/app.js', 'js')
.sass('resources/assets/sass/app.scss', 'css');
