我在php7.0上使用Laravel 5.2以及何时

我尝试使用Laravel excel（http://www.maatwebsite.nl/laravel-excel）。像这样：

public function export(){
    $users = User::with('roles')->get();

    $excel = Excel::create('beo_felhasznalo_export'. date('_Y-m-d_H-i-s'));

    //header
    $excel->appendRow(array(
        'felhasználónév', 'valódi név', 'e-mail', 'mobil', 'felhasználói szint'
    ));

    foreach($users as $user){
        $excel->appendRow(array(
            $user->username,
            $user->real_name,
            $user->email,
            $user->mobile_number,
            implode(',', $user->roles())
        ));
    }
    $excel->download('xls');
}

我收到此错误：

Illuminate\Contracts\Container\BindingResolutionException thrown with message "Target [Illuminate\Contracts\Bus\Dispatcher] is not instantiable."
