我正在使用RHEL8 AMI运行EC2实例。
我正在实例上安装R，并且我相信我需要EPEL软件包并通过以下两个命令启用代码就绪构建器
sudo dnf install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf config-manager --set-enabled rhui-codeready-builder-for-rhel-8-rhui-rpms
更多信息，请访问[https://aws.amazon.com/premiumsupport/knowledge-center/ec2-enable-epel/）
我可以很好地下载epel（第一行），但是运行第二行时，我得到以下信息：
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Error: No matching repo to modify: rhui-codeready-builder-for-rhel-8-rhui-rpms.
此外，当我尝试运行以下命令时，也会得到以下信息：
This system has no repositories available through subscriptions.
为了完整性，这是我尝试安装R时的错误
$sudo yum install -y R
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

Error:

(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
有人有什么想法或已经解决了相同的问题吗？
我刚写完就解决了...
供任何人参考，似乎AWS的命令写错了。
仍然如上所示下载epel软件包
sudo dnf安装-y https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
并且代替AWS网站上的以下内容
sudo dnf config-manager --set-enabled rhui-codeready-builder-for-rhel-8-rhui-rpms
您可以使用
sudo dnf config-manager --set-enabled codeready-builder-for-rhel-8-rhui-rpms
然后继续执行sudo yum install -y R
