Installing Ruby Gems under Ruby 1.9 [Windows]

Ruby

Hi,
Has anyone gotten gems to install correctly using Ruby 1.9?

I have the latest Ruby 1.9 binary, and Ruby Gems.

When I run “ruby setup.rb” I get an error message like this:

setup.rb:18: command not found: (null)
setup.rb:18:in exec': No such file or directory (Errno::ENOENT) from setup.rb:18:in’

Thanks very much for your help

So I from some more reading, I discovered that Ruby Gems comes
pre-installed with 1.9.

Here’s my real stumbling point then I guess:

Has anybody managed to install QTRuby with Ruby 1.9 on Windows? I’m
having an awful lot of trouble, and information is scarce.
