您的要求无法解决为作曲家中的一组可安装软件包错误

Question

在我的 laravel 应用程序中，我想使用 laravel-notification-channels /fcm 启用 fcm，这个 package 现在使用 kreait/laravel-firebase 用于 ZBF12E1515C25C7D8C0352F1415 凭据设置。AB

首先，我安装了 laravel 通知 package 没有问题，使用以下命令：

composer require laravel-notification-channels/fcm:~2.0

现在，当我尝试使用以下命令安装 laravel-firebase 时：

composer require kreait/laravel-firebase

我在命令提示符中收到以下作曲家警告：

Warning from https://repo.packagist.org: You are using an outdated version of Composer. Composer 2.0 is now available and you should upgrade. See https://getcomposer.org/2

    - Installation request for laravel-notification-channels/fcm (locked at 2.1.1, required as ~2.0) -> satisfiable by laravel-notification-channels/fcm[2.1.1].


Installation failed, reverting ./composer.json to its original content.

我怎样才能解决这个问题？

Answer 1

当运行composer require laravel-notification-channels/fcm:~2.0时，package kreait/laravel-firebase自动安装。

当我现在运行composer require kreait/laravel-firebase它只是说

composer require kreait/laravel-firebase
Using version ^3.0 for kreait/laravel-firebase
./composer.json has been updated
Running composer update kreait/laravel-firebase
Loading composer repositories with package information
Updating dependencies
Nothing to modify in lock file
Writing lock file
Installing dependencies from lock file (including require-dev)
Nothing to install, update or remove

错误不是来自这两个包。
