Не удалось запустить установку rhc

Я не могу выполнить команду «rhc setup» после установки gem. Я использовал установщик Windows с сайта rubyinstallersr.org. См. вывод ниже после выполнения настройки rhc:

>     C:\Users\Admin>rhc setup
>     /usr/lib/ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find rh
>      (>= 0) amongst [bigdecimal-1.1.0, io-console-0.3, json-1.8.0, minitest-2.5.1,

>             from /usr/lib/ruby/1.9.1/rubygems/dependency.rb:256:in `to_spec'

>             from C:/Ruby200-x64/bin/rhc:22:in `<main>'

Установка Gem прошла успешно. См. вывод ниже:

Нужен совет, как исправить эту ошибку.
