r - EPEL & Codeready-builder AWS EC2 RHEL8

问题描述

我正在使用 RHEL8 AMI 运行 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 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（https://aws.amazon.com/premiumsupport/knowledge-center/ec2-enable-epel/）

我可以很好地下载 epel （第一行），但是当我运行第二行时，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.

此外，当我尝试运行以下命令时，我得到以下信息：

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

This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

有没有人有任何想法或解决了同样的问题？

解决方案

刚写完就解决了。。。

供任何人参考，AWS 的命令似乎写错了。

还是下载epel包如上图

sudo dnf install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

而不是来自AWS网站的以下内容

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 sudo yum install -y R
