How to Install Ruby on Fedora 31/30/29 with RVM. Ruby is a dynamic, object-oriented programming language. We are using RVM, which stands for Ruby Version Manager, which makes easier to install Ruby on Linux platform. RVM is also helpful for managing multiple version of Ruby without conflicting, and we can switch the system to any version of Ruby using a single command.
This tutorial will help you to install Ruby stable release on your Fedora systems using RVM.

sudo -i dnf install gcc-c++ patch readline readline-devel zlib zlib-devel \ libyaml-devel libffi-devel openssl-devel make \ bzip2 autoconf automake libtool bison sqlite-devel
Step 2 – Install RVM
