Damaged app.js after php artisan ui vue

I created a new project: laravel new vue-app

And installed laravel/ui, after that I executed command: php artisan ui vue.

And app. js has this content:

namespace Illuminate\Auth\Events;

use Illuminate\Queue\SerializesModels;

class Verified
{
    use SerializesModels;

    /**
     * The verified user.
     *
     * @var \Illuminate\Contracts\Auth\MustVerifyEmail
     */
    public $user;

    /**
     * Create a new event instance.
     *
     * @param  \Illuminate\Contracts\Auth\MustVerifyEmail  $user
     * @return void
     */
    public function __construct($user)
    {
    $this->user = $user;
    }
}
