Install Ruby's 3 way (yum, rbenv, rvm)

1. I recommend to use rbenv to install ruby

First Need to install rbenv's package

sudo dnf install git wget gcc bzip2 openssl-devel libffi-devel readline-devel zlib-devel gdbm-devel ncurses-devel

type y to install 32 package (Install 39 package)

Use wget to install rbenv & ruby-build

(Don's use)wget -q https://github.com/rbenv/rbenv-installer/raw/master/bin/rbenv-installer -O- | bash

(Reference https://github.com/rbenv/rbenv-installer)
wget -q https://github.com/rbenv/rbenv-installer/raw/HEAD/bin/rbenv-installer -O- | bash

Then add environment to add this path

echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
(Don't Use)echo 'eval "$(rbenv init -)"' >> ~/.bashrc
echo 'eval "$(rbenv init - bash)"'
source ~/.bashrc

check rbenv is installed or not

wget -q https://github.com/rbenv/rbenv-installer/raw/HEAD/bin/rbenv-doctor -O- | bash

Check How rbenv's ruby had been install

rbenv -L
