composer需要appointer/swaggervel——laravel v7.0的开发问题

当我运行命令

composer require appointer/swaggervel--dev

将这个包添加到我的项目中时，我遇到了这个错误

 Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for appointer/swaggervel ^2.5 -> satisfiable by appointer/swaggervel[v2.5].
    - Conclusion: remove laravel/framework v7.8.1
    - Conclusion: don't install laravel/framework v7.8.1

我不明白这个错误是什么，以及如何纠正它

提前谢谢你回答我的问题

注意：这是我的composer.json文件：

    "php": "^7.2.5",

这意味着您尝试安装的软件包不支持您当前版本的Laravel（7.8.1）

您可以在下面看到软件包的代码：

此错误可以通过取消此选项来解决

您可以向包的作者请求更新依赖项以支持laravel 7.8.1，或者您可以分叉他们的存储库并更新自己的需求&发布新分叉包另一种解决方案是在您的项目中使用laravel 6

    "require": {
        "php": ">=5.6.0",
        "illuminate/support": "^5.0|^6.0",
        "swagger-api/swagger-ui": "^3.1",
        "zircote/swagger-php": "^2.0"
    },

composer require dagbouj-hatem/swaggervel --dev
