我最近开始使用 Laravel。请忽略我的错误。

【解决方案1】：

根据https://packagist.org/packages/brozot/laravel-fcm 列出的包依赖项（以及根据您发布的消息），此包在 v1 中需要 Monolog，但目前您在 v2 中安装了 Monolog。

要解决这个问题，您应该询问软件包维护者该软件包是否可以支持最新版本的 Monolog（已在 https://github.com/brozot/Laravel-FCM/issues/152 中作为错误报告列出），或者您将安装的版本降级到 v1。但根据那个错误报告，我假设该包与 Laravel 6 不兼容

谢谢。我试图将我的独白版本降级到 v 1.19。现在它很容易安装。
