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，因为它需要libyaml-devel和libffi-dev。每当我试图安装它们时，我都会发现没有找到任何软件包的错误。

Answer 1

libyaml-devel和libffi-devel是由默认禁用的CentOS 8's PowerTools提供的。

因此，一个简单的yum --enablerepo=powertools install libyaml-devel libffi-devel应该能做到这一点。

(其他答案发布时，情况可能并非如此。)

Answer 2

您没有运行CentOS。您正在运行没有订阅的RHEL6。与您的sysadmin联系以获得添加的订阅，您将能够添加包。我不建议您从IP地址的任意FTP服务器安装CentOS包。你不知道你得到了什么，你也没有检查RPM签名。

如果您打算安装CentOS，也许您应该从CentOS媒体重新安装系统。

Answer 3

对于RHEL6来说，这两种方法都可以在“流变-6-服务器-可选-rpms”存储库中找到，我不建议使用诸如"jsbillings“这样的未知RPM源。

subscription-manager repos --enable rhel-6-server-optional-rpms
