laravel - 安装简单的二维码后， Blade 引擎无法在 laravel 5 上运行

Question

安装照亮/html后，我的 Blade 引擎运行良好。但是当我通过以下方式安装简单的 qrCode 时:

"require": {
    "simplesoftwareio/simple-qrcode": "~1"
}

我收到此错误:

Class 'Illuminate\Html\HtmlServiceProvider' not found

安装后终端的输出，简单的二维码是:

在此错误发生后，我还运行了composer require说明/html。但我遇到了同样的错误。

您的 composer.json 文件有两个 require 键，如问题中的 Composer 错误中所述:

Key require is a duplicate in ./composer.json at line 53

删除以获得正确格式的composer.json 文件并重试。
