Answer 1

你composer.json文件有两个require密钥，如作曲家错误中提到你的问题：

主要要求是在第53行

删除./composer.json重复有一个正确形成的作曲家。 json文件并重试。

Answer 2

您正在为Laravel 5项目安装Laravel 4的模块。 html包从Laravel 5.删除

你可以找另一个包，或者你可以install Html package和适应用QR码来Laravel工作5

Answer 3

行“simpleoftwareio/simple-qrcode”：“〜1”必须位于您的composer.json中的“require”中。
