The Windows platform has several options for installing Ruby. The first option is simply installing the compiled binaries. The second option is to use the one-click installer. If you’re unsure about how to install Ruby, the RubyInstaller may be the best option for you. (In addition to Ruby, the RubyInstaller also comes with a bunch of additional libraries built in.)
