致命错误：类'；Collective\Html\HtmlServiceProvider'；与heroku一起部署时在Laravel中找不到

这是我的composer.json：

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],

    },

        ]
    },
    "config": {
        "preferred-install": "dist"
    }
}

问题是：

[Symfony\Component\Debug\Exception\FatalThrowableError]

remote:

将新提供程序添加到config/app.php的提供程序数组：

  'providers' => [
    // ...
    Collective\Html\HtmlServiceProvider::class,
    // ...
  ],

'aliases' => [
    // ...
      'Form' => Collective\Html\FormFacade::class,
      'Html' => Collective\Html\HtmlFacade::class,
    // ...
  ],

将两个类别名添加到config/app.php的别名数组中：

  'providers' => [
    // ...
    Collective\Html\HtmlServiceProvider::class,
    // ...
  ],

'aliases' => [
    // ...
      'Form' => Collective\Html\FormFacade::class,
      'Html' => Collective\Html\HtmlFacade::class,
    // ...
  ],

首先通过Composer安装此软件包。编辑项目的composer.json文件以要求laravelcollective/html

使用此命令

composer require "laravelcollective/html":"^5.4.0"

接下来，将您的新提供者添加到config/app.php的提供者数组中：

  'providers' => [
    // ...
    Collective\Html\HtmlServiceProvider::class,
    // ...
  ],

  'aliases' => [
    // ...
      'Form' => Collective\Html\FormFacade::class,
      'Html' => Collective\Html\HtmlFacade::class,
    // ...
  ],

将两个类别名添加到config/app.php的别名数组中：

  'providers' => [
    // ...
    Collective\Html\HtmlServiceProvider::class,
    // ...
  ],

  'aliases' => [
    // ...
      'Form' => Collective\Html\FormFacade::class,
      'Html' => Collective\Html\HtmlFacade::class,
    // ...
  ],
