EPEL和Codeready builder AWS EC2 RHEL8

我正在运行一个带有RHEL8AMI的EC2实例

我希望在实例上安装R，我相信我需要EPEL包，并通过以下两个命令启用codeready builder

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

我可以很好地下载epel第一行，但当我运行第二行时，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. 

This system has no repositories available through subscriptions.

此外，当我尝试运行以下操作时，我会得到以下结果：

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. 

This system has no repositories available through subscriptions.

为了完整起见，这是我尝试安装R时的错误

$sudo yum install -y R

有没有人有什么想法或解决了同样的问题？

我刚写完就解决了这个问题

作为任何人的参考，似乎AWS的命令写错了

仍然下载epel包，如上所示

sudo dnf安装-y

而不是AWS网站上的以下内容

sudo dnf config-manager --set-enabled rhui-codeready-builder-for-rhel-8-rhui-rpms

你可以用

sudo dnf config-manager --set-enabled codeready-builder-for-rhel-8-rhui-rpms

然后继续使用sudo yum安装-y R
