After running:
sudo dnf install ruby ruby-devel rubygems nodejs
sudo dnf group install "C Development and Tools"
I was unable to install Jekyll via `gem` due to an error:
The compiler failed to generate an executable file. (RuntimeError) You have to install development tools first.
Taken from the [fedoraproject.org](https://developer.fedoraproject.org/tech/languages/ruby/gems-installation.html) Gem page:
>If you installed all the above, but the extensions would still not compile, you are probably running a Fedora image that misses `redhat-rpm-config` >package. In that case gcc compiler would complain about one of the following:
gcc: error: conftest.c: No such file or directory
gcc: error: /usr/lib/rpm/redhat/redhat-hardened-cc1: No such file or directory
>To solve this, simply run sudo dnf install `redhat-rpm-config`.
After doing so it downloaded, compiled and installed without a problem.
