The RubyInstaller Development Kit is a toolkit that makes it easy to build and use native C/C++ extensions such as RDiscount and Nokogiri for Ruby on Windows. Alternatively a manual download and installation from MSYS2 is also possible. It can be installed through the ridk install command, which is part of RubyInstaller-2.4. Stating with RubyInstaller-2.4 we’re no longer using our own DevKit compilation, but make use of MSYS2 for both building Ruby itself as well as building Ruby gems with C-extensions. The DevKit that’s who! MSYS2-DevKit (only Ruby >= 2.4) Sometimes you just want RubyGems to build that cool native, C-based extension without squawking.
