【问题讨论】：

这个问题看起来你已经预先安装了webonyx/graphql-php，并且你的版本与它的 Lighthouse 版本有冲突。
我遇到了同样的错误。原因是我安装了另一个 graphql 包。 rebing/graphql-laravel。一旦我删除安装工作正常。

标签： laravel graphql laravel-lighthouse

【解决方案1】：

如果你有一个现有的 Laravel 5.7 项目，你真正需要的只是两个步骤：

通过composer require nuwave/lighthouse安装
在graphql/schema.graphql 中定义您的架构

根据nuwave/lighthouse包你需要php: >= 7.1

除此之外，你还需要在你的项目中完成包的需求
