I’m looking into learning some Ruby, I’ve installed it on Windows 7 X64 using the installer you can find at RubyInstaller.org .

Now my problem is that the installation is done and all that. But when I try and check for the ruby version in command prompt e.g 

ruby -v

I just get an error saying that my system doesn’t know what that is. Including ruby -e and ruby -s etc… Now coming from a Java background I assume that this has something to do with environment variables that might not be set for Ruby?

How exactly does one go about this to quickly get set up?

    Try to edit your PATH variable. My PATH variable contain C:\Ruby192\bin, in this folder there are files ruby and irb.

    Also I think there is an option for that in the installator, which you may check.
