【问题描述】：

我正在使用以下文档将 laravel 4.2 升级到 5.0：

http://laravel.com/docs/master/upgrade#upgrade-5.0

我完成了这些点：Controllers，Route Filters

比之后以下错误来了：

【问题讨论】：

ProviderRepository.php 第 150 行中的 FatalErrorException：找不到类 'Illuminate\Html\HtmlServiceProvider'
HtmlServiceProvider 的错误是因为 HtmlBuilder 不再包含在核心中。你需要在作曲家中要求illuminate/html

标签： upgrade laravel-5

【解决方案1】：

完成升级。稍后在文档中，您可以找到以下内容：

表单和 HTML 助手

如果您使用的是表单或 HTML 帮助程序，您将看到一个错误说明找不到类“表单”或找不到类“Html”。要解决此问题，请添加 "illuminate/html": "~5.0" 到您的 composer.json 文件的要求部分。

您还需要添加表单和 HTML 外观和服务提供者。编辑 config/app.php，并将这一行添加到 'providers' 数组：

'Illuminate\Html\HtmlServiceProvider'，接下来，将这些行添加到 “别名”数组：

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