安装后，打开错误了？

No hint path defined for [sudosu]. (View: /Users/powercen/sites/larabbs/resources/views/layouts/app.blade.php) (View: /Users/powercen/sites/larabbs/resources/views/layouts/app.blade.php)

查看了下，是app.blade.php里面出错了

    @if (app()->isLocal())
        @include('sudosu::user-selector')
    @endif

我注释掉,没有报错了
sudosu::user-selector 是什么写法？什么意思？
