首先将此行添加到 composer.json

 illuminate / html：〜5.0
 

然后执行 composer更新
等待更新完成，然后打开 config / app.php add this：

 'Illuminate\Html\HtmlServiceProvider'，
 / pre> 

到 providers 数组和：
 'Form'=> 'Illuminate\Html\FormFacade'，
'Html'=> '别名      code>数组，并确保在刀片式服务器中使用Html或在小写Html而不是HTML中使用Html

Im trying to add the HtmlServiceProvider with Laravel 5.
I keep getting the following error:

FatalErrorException in compiled.php line 6391:
Class 'Illuminate\Html\HtmlServiceProvider' not found

This is how my providers look like:
'providers' => [

    /*
     * Laravel Framework Service Providers...
     */
    'Illuminate\Foundation\Providers\ArtisanServiceProvider',
    'Illuminate\Auth\AuthServiceProvider',
    'Illuminate\Bus\BusServiceProvider',
    'Illuminate\Cache\CacheServiceProvider',
    'Illuminate\Foundation\Providers\ConsoleSupportServiceProvider',
    'Illuminate\Routing\ControllerServiceProvider',

    'Illuminate\Validation\ValidationServiceProvider',
    'Illuminate\View\ViewServiceProvider',
    'Illuminate\Html\HtmlServiceProvider',

    /*

    'App\Providers\BusServiceProvider',
    'App\Providers\ConfigServiceProvider',
    'App\Providers\EventServiceProvider',
    'App\Providers\RouteServiceProvider',

],

This is how my aliases look ik app.php:

    'Form'      => 'Illuminate\Html\FormFacade',
    'Html'      => 'Illuminate\Html\HtmlFacade',

],

At last i have added this inside my composer.json
"require": {
    "laravel/framework": "5.0.*",
    "illuminate/html": "~5.0"
},

Somehow i keep getting this error so im hoping someone can help me out with this :)

Thanks in advance!

First add this line to composer.json
"illuminate/html": "~5.0"

Then do a composer update
Wait for the update to finish, then open config/app.php add this:
'Illuminate\Html\HtmlServiceProvider', 

to the providers array and this:
'Form'      => 'Illuminate\Html\FormFacade',
'Html'      => 'Illuminate\Html\HtmlFacade',

to the aliases array, and be sure when you use Html in blade or wherever use it in lowercase 'Html' not HTML
