About:
ruby-install is a command-line utility designed to simplify the installation of various Ruby interpreters from source code. It automates the process of downloading, extracting, compiling, and installing specific Ruby versions, including MRI, JRuby, and Rubinius. The tool provides a straightforward alternative to version managers like RVM or rbenv for users who prefer a more direct installation method.

Key Features:

Supports multiple Ruby implementations (MRI, JRuby, Rubinius, TruffleRuby, mruby)
Installs Ruby versions into isolated, version-specific directories
Automates dependency resolution and compilation from source
Provides a simple, dependency-free shell script implementation

Use Cases:

Setting up specific Ruby versions for development environments without a version manager
Installing Ruby interpreters on servers or in CI/CD pipelines
Managing multiple Ruby implementations side-by-side on a single system

Alternatives:

rbenv – rbenv manages multiple versions via shims, whereas ruby-install performs standalone installations.
RVM – RVM is a more feature-rich tool that includes gemset management, while ruby-install focuses solely on installing the Ruby interpreter itself.
