How To Install rubygem-concurrent-ruby on CentOS 8
rubygem-concurrent-ruby is Modern concurrency tools for Ruby
Introduction
In this tutorial we learn how to install rubygem-concurrent-ruby on CentOS 8.
What is rubygem-concurrent-ruby
Modern concurrency tools including agents, futures, promises, thread pools, actors, supervisors, and more. Inspired by Erlang, Clojure, Go, JavaScript, actors, and classic concurrency patterns.
We can use yum or dnf to install rubygem-concurrent-ruby on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install rubygem-concurrent-ruby.
Install rubygem-concurrent-ruby on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
The output should look something like this:
