我将一个软件包上传到packagist，并运行以下命令以在全球范围内对其进行要求：
composer global require emmajiugo/flutterwave-cli
此操作失败，并显示以下输出：
Changed current directory to /Users/emmanuelezejiugo/.composer

我尝试更改composer.json文件中的一些内容，但仍然遇到问题。以下是我的composer.json文件：

答案 0 :(得分：3)
您是否尝试阅读错误消息？一行告诉您问题所在：
emmajiugo / flutterwave-cli v1.3需要laravel-zero / framework ^ 7.0
另一方面，您的composer.json要求"laravel-zero/framework": "^5.8"-这两个要求显然不能同时使用。您应该在您的库中需要较低版本的Laravel，或者在您的应用程序中需要较高版本的Laravel
答案 1 :(得分：2)
Composer的“全局安装”功能通过在特定目录中设置Composer项目并以常规方式进行管理来工作。为the manual states：
全局命令允许您像在COMPOSER_HOME目录中一样运行其他命令，例如安装，删除，要求或更新。
这仅仅是管理存储在中央位置的项目的助手，该项目可以容纳您想在任何地方使用的CLI工具或Composer插件。
这是理解您所看到的输出的关键，它开始于：
将当前目录更改为/Users/emmanuelezejiugo/.composer
此后发生的所有情况，就像您在该目录中运行常规的composer命令一样。
冲突的第一部分很简单：
导致冲突的原因显示在消息末尾：
这是指您将软件包“锁定”到composer.json 中用于您当前正在安装软件包的项目的特定版本。换句话说，您正在尝试为该项目添加两个相互矛盾的需求。
如上所述，该项目不是您的新库，而是您在/Users/emmanuelezejiugo/.composer中创建的项目。因此，您需要更改的配置位于/Users/emmanuelezejiugo/.composer/composer.json中。
最简单的解决方案可能是不将库安装在该文件夹中。如上所述，composer global命令实际上除了为您更改目录外没有做任何事情；在大多数情况下，最好只为每个项目或工具创建一个目录，并在该目录中要求其依赖性，即使您只需要本地副本即可运行某些命令。

谢谢。
我运行了composer global update，它更新了所有必需的软件包。
然后composer global require repo-name/repo-package-name做起来就很好了。
