install RBenv

clone the repo

cd ~
git clone https://github.com/rbenv/rbenv.git ~/.rbenv

add load script to ~/.bashrc and re-source shell

echo '' >> ~/.bashrc
echo '# adding rbenv load script' >> ~/.bashrc
echo 'eval "$(~/.rbenv/bin/rbenv init - bash)"' >> ~/.bashrc
source ~/.bashrc

(make sure you run these instructions in the same terminal tab/window that you source ~/.bashrc with rbenv loaded.)

git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build

install needed dependencies for compiling ruby

sudo dnf update -y
sudo dnf install make automake gcc gcc-c++ kernel-devel libyaml-devel -y
