Question

我当前正在尝试使用以下命令安装Bogardo \ Mailgun作曲家软件包：

composer require bogardo/mailgun

但是，运行命令后，依赖项存在问题，我不确定如何解决此问题，因为我对Composer的经验不足。使用npm，我有npm audit fix命令，该命令可解决所有冲突，但是如何在此处解决m问题？

这是我的命令提示符显示的内容：

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

Answer 1

由于Laravel requires Carbon 2.x和your (outdated) package requires Carbon 1.x存在冲突。最简单的解决方案是使用另一种类似于以下官方工具的mailgun软件包：https://github.com/mailgun/mailgun-php

编辑：Laravel甚至不需要其他软件包，开箱即用地支持Mailgun！

编辑2： Laravel也可以使用1.x版本，但选择不使用。老实说，我不知道如何强制Laravel使用旧版本

在laravel中使用composer发行Mailgun \ Bogardo软件包安装问题
