RubyInstaller is the most popular way to install Ruby on Windows. It provides a self-contained, easy-to-use environment for running Ruby applications without the need for additional dependencies.

Features

Simple Installation: RubyInstaller includes everything needed to set up a Ruby development environment on Windows.

MSYS2 Integration: Provides access to development tools, including compilers and libraries, enabling the use of native Ruby gems.

Precompiled Binaries: Eliminates the need to compile Ruby from source.

Multiple Ruby Versions: Supports various Ruby versions, allowing developers to work with different versions as needed.

Key Components

Ruby Executable - The core Ruby runtime.

Bundled DevKit (MSYS2) - A collection of development tools needed for compiling native extensions.

Gem Management - Supports gem install for package management.

IRB (Interactive Ruby Shell) - A REPL for experimenting with Ruby code interactively.

Specifically, the goals of the RubyInstaller are:
  • Provide an easy-to-use Windows installer for quickly and painlessly installing a fully functioning baseline MRI Ruby environment on Windows platforms.
  • Provide an optional Development Kit for those interested in building mswin32-compatible Ruby extensions natively on Windows platforms using an MSys/MinGW-based toolchain.
  • Provide a build environment via this project and complementary projects like rake-compiler to help developers easily build Ruby and Ruby C extensions from source code.
  • Add value to the growing community of Windows-based Ruby developers by providing a place that summarizes the hard-won lessons and issues with building Ruby and Ruby C extensions natively on Windows.
