mix.scripts is not working (webpack.mix.js)

i have the following webpack.mix.js:

const { mix } = require('laravel-mix');
mix.scripts([
    'resources/assets/js/app.js',
    'resources/assets/js/definers.js',
    'resources/assets/js/tab_system.js',
    'resources/assets/js/searchbox.js',
    'node_modules/angular/angular.js',
], 'public/js/app.js', 'public/js');

mix.js('resources/assets/js/afegir_caracteristica_visuals.js', 'public/js')
    .js('resources/assets/js/afegir_categoria_visuals.js', 'public/js')
    .js('resources/assets/js/afegir_localitat_visuals.js', 'public/js')
    .js('resources/assets/js/afegir_tipo_visuals.js', 'public/js')
    .js('resources/assets/js/afegir_transaccio_visuals.js', 'public/js')
    .js('resources/assets/js/eliminar_element.js', 'public/js');

mix.styles([
    'resources/assets/css/tab_system.css',
    'resources/assets/sass/app.scss',
], 'public/css/app.css');
