Ruby remains one of the most popular programming languages for web development, automation, and software engineering. If you want to Install Ruby Ubuntu, there are several reliable methods available depending on your development requirements. Whether you need a quick installation or support for multiple Ruby versions, Ubuntu offers flexible options for every workflow.
This guide explains three practical ways to install Ruby on Ubuntu 20.04, including installation through Ubuntu repositories, Rbenv, and RVM.
Ruby is widely recognized for its clean syntax and developer-friendly approach. It powers numerous applications and frameworks, including Ruby on Rails, which is commonly used for building modern web applications.
Ubuntu provides a stable environment for Ruby development, making it a preferred platform for developers, startups, and enterprise teams.
The fastest way to install Ruby is through Ubuntu’s official package repositories. This method is ideal for users who need a stable Ruby version without additional configuration.
Begin by updating your package index and installing the Ruby package:
sudo apt updatesudo apt install ruby-full
After installation, verify the version:
ruby --version
This approach is simple and reliable, though the repository version may not always include the latest Ruby release.
For developers managing multiple projects, Rbenv provides a lightweight solution for switching between Ruby versions.
First, install the required build dependencies:
sudo apt updatesudo apt install git curl build-essential libssl-dev zlib1g-dev
Next, install Rbenv and the ruby-build plugin. Once configured, you can view available Ruby versions and install a specific release.
Example:
rbenv install 3.1.0rbenv global 3.1.0
Rbenv allows you to define Ruby versions globally, locally within a project, or only for the current shell session. This flexibility makes it a popular choice among professional developers.
Another powerful option is Ruby Version Manager (RVM). Unlike Rbenv, RVM includes additional features for managing Ruby environments and gemsets.
After installing the necessary dependencies, download and configure RVM. Then install the preferred Ruby version:
rvm install rubyrvm --default use ruby
RVM is especially useful when working on multiple Ruby applications that require separate environments.
Each installation method serves a different purpose:
If you’re building applications with Ruby on Rails or maintaining several projects, Rbenv or RVM will provide greater flexibility than the default Ubuntu package.
When you need to Install Ruby Ubuntu, choosing the right method depends on your workflow and project requirements. Ubuntu repositories offer a straightforward setup, while Rbenv and RVM provide advanced version management capabilities. By selecting the approach that matches your development environment, you can create a stable and efficient Ruby platform for building modern applications.
