升级Ruby至2.7后重新安装Passenger遭遇依赖冲突问题求助

各位大佬好，我最近在升级Ruby版本的时候遇到了个棘手的问题，想请教下大家怎么解决😅

原本我想把系统里的Ruby 2.5升级到Ruby 2.7，但Passenger阻碍了这次升级——用yum执行升级时直接报错了。于是我先卸载了Passenger和Ruby 2.5，之后顺利装上了Ruby 2.7。

结果新的问题来了：现在我没法重新安装Passenger了，相当于把错误转移了位置😂

我执行了这条安装命令：

sudo yum -y install passenger

得到的报错信息如下：

passenger                                                                        2.7 kB/s | 833  B     00:00

Error:

我按照Passenger官方文档的步骤，先移除了Passenger的仓库，重新安装了一遍，但还是没用。

现在我的感觉是，系统里还有某个地方绑定着Ruby 2.5的依赖，导致Passenger安装时一直找这个版本的库，但我已经换成2.7了。

我的系统当前的仓库列表如下：

• appstream CentOS Stream 8 - AppStream
• baseos CentOS Stream 8 - BaseOS
• docker-ce-stable Docker CE Stable - x86_64
• docker-ce-test Docker CE Test - x86_64
• epel Extra Packages for Enterprise Linux 8 - x86_64
• epel-next Extra Packages for Enterprise Linux 8 - Next - x86_64
• extras CentOS Stream 8 - Extras
• extras-common CentOS Stream 8 - Extras common packages
• passenger passenger
• powertools CentOS Stream 8 - PowerTools
• remi-modular Remi's Modular repository for Enterprise Linux 8 - x86_64
• remi-safe Safe Remi's RPM repository for Enterprise Linux 8 - x86_64
