RubyInstaller

RubyInstaller is the easiest and most used environment in Windows. Ruby is a great language for beginners and professionals alike. It is suitable for small scripts and large applications. RubyInstaller combines the capabilities of native Windows programs with a rich set of UNIX tools, MSYS2 and a large repository of MINGW libraries. It's a great foundation for development and production use, especially if you want to use Ruby for everyday scripting or require access to Windows resources such as hardware devices, DLLs, OLE, GUIs, or GPUs.
