Module or Group 'development-tools' is not available

Good evening Geeks.

I get this error when I run the following command:

$ sudo dnf install ruby ruby-devel openssl-devel redhat-rpm-config @development-tools

Module or Group 'development-tools' is not available.
Error: Nothing to do.

My goal is to install Jekyll CMS on Rocky Linux 9 and I have to begin by installing the prerequisites.

Please assist.

I can duplicate your error, using your command. I can, though, install development tools separately with:

dnf groupinstall "Development Tools"

I’m assuming that you want just those development packages you mentioned in your command, rather than the whole suite. This command works, but I believe it still installs the entire suite of dev tools:

sudo dnf install ruby ruby-devel openssl-devel redhat-rpm-config @"Development Tools"
