无法在 CentOS 中安装 libyaml-devel libffi-devel

Question

我正在尝试通过 RVM 安装最新的 ruby​​。我无法安装 install，因为它需要 libyaml-devel 和 libffi-dev。当我尝试安装它们时，我收到错误消息，没有找到包

[root@dev workspace]# rvm requirements

Answer 1

libyaml-devel由 CentOS 8 的 PowerTools-repository提供libffi-devel，默认情况下禁用。

所以一个简单的方法yum --enablerepo=powertools install libyaml-devel libffi-devel就可以解决问题。

（也许发布其他答案时情况并非如此。）
