Download Issues?

Depending on your location, sometimes the downloads will not work. This is due RubyForge provided mirrors. Until we completely move our releases out of them. please add /noredirect at the end of the URL and try again.

Sorry the inconvenience.

Speed and Compatibility

RubyInstaller is compiled with MinGW which offers improved speed and better RubyGem compatibility, including support for many more native C-based extensions such as Ruby FFI, Nokogiri, FXRuby and many others.

Convenience

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 archived versions or the Ruby documentation, you will need to download 7-Zip from the 7-Zip website.

Documentation

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

Build Your Own Native Extensions

The RubyInstaller Development Kit (DevKit) is a MSYS/MinGW based toolkit than enables you to build many of the native C/C++ extensions available for Ruby.

Support

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