laravel试图组件开发错误

Question

  laravel 中App/http/ViewComposer 添加组件代码<?phpnamespace App\Http\ViewComposer;use Illuminate\Contracts\View\View;class ViewComposer{    public function compose(View $view)    {        //$chq = 'gljglkdflgjdfl';        //$view->with('navi',compact('chq'));         $view->with('chq','jgldjsglfsdjlgfds');        //$view->withNmae('navi');    }}服务中注册代码：<?phpnamespace App\Providers;use Illuminate\Support\ServiceProvider;use DB,View;class ViewServiceProvider extends ServiceProvider{    /**     * Bootstrap the application services.     *     * @return void     */    public function boot()    {        /*View::composer('navi', function($view){            $view->with('chq', 'jvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv');        });*/        View::composer('navi', 'App\Http\ViewComposer\ViewComposer');    }    /**     * Register the application services.     *     * @return void     */    public function register()    {        //    }}同时在app.php中也添加了相应的代码App\Providers\ViewServiceProvider::class,但是我在调用navi这个视图中调用{{$chq}}的时候报错了，这个是怎么回事
