Download the RubyInstaller

Both the executable and 7-Zip archive versions of the RubyInstaller for Windows have been compiled with version 3.4.5 of the MinGW compiler toolset rather than the outdated Visual Studio 6 toolkit used to build the legacy One-Click Installers.

As a result, the RubyInstaller's are much more performant than the old One-Click Installers and more compatible with many more binary RubyGems such as Ruby FFI, Nokogiri, FXRuby and others. We maintain a list of native C-based RubyGems that we've found to be compatible with the RubyInstaller at our RubyInstaller project site.

As an added convenience for Windows users, we've made available the Ruby Core and Standard Library documentation in Compiled HTML Help (CHM) format.

The RubyInstaller Development Kit (DevKit) is a MinGW and MSYS based environment than enables you to build many of the native C-based extensions available for Ruby. It is not meant to be a general purpose MSYS/MinGW installation.

No additional software is needed if you want to use the executable versions of the RubyInstaller. If you would like to use the 7-Zip archive versions of the RubyInstaller, the DevKit, or the Ruby documentation, you will need to download 7-Zip from the 7-Zip website.

Enjoy, happy Ruby coding, and let us know what you think or if you have any issues at our RubyInstaller Google Group.
