Composer 更新正在尝试删除根包答案

【问题标题】：Composer update is trying to remove the root packageComposer 更新正在尝试删除根包
【发布时间】：2023-03-30 16:28:01
【问题描述】：

我正在尝试安装 3 个软件包，其中 1 个是我在 GitHub 上分叉的。安装失败，错误消息说删除根包和我所在的 git 分支（开发），这是没有意义的。

我尝试了什么：

删除 composer.lock
删除供应商文件夹
执行 composer clearcache 命令
尝试一个空白项目：它可以工作

总之，在一个空白项目上它可以正常工作，但在我的其他项目（esynaps/api-v2.e-synaps.com）上却不行。

错误信息：

【问题讨论】：

您是否尝试过删除 composer.lock 以及供应商文件夹并进行全新的 composer 安装？锁文件会导致这种事情
对不起，我忘了说：是的，我还删除了 composer.lock
你的 PHP 版本是多少（显示php -v 的结果）？你想用这个replace 配置实现什么？

感谢您让我走上正轨。我从我的项目（api-v2）中删除了“替换”对象，它似乎有效。当我昨天尝试时，我遇到了冲突，我添加了替换，但我没有更多了。如果您希望我将其标记为已接受，请发布答案。

【解决方案1】：

感谢rob006 的帮助。只需删除 composer.json 中的“替换”属性。该属性的用途被误解了。

https://getcomposer.org/doc/04-schema.md#replace

列出被此包替换的包。这允许您分叉一个包，以具有自己版本号的不同名称发布它，而需要原始包的包继续使用您的分叉，因为它替换了原始包。
