【问题描述】：

我需要使用 openshift 来部署 Web 应用程序并修改用于数据库连接的文件并安装 RHC。但无法设置。我安装了rbenv，但真的不知道如何使用。我的mac是1周买的。基本上，安装的软件不多。完整的错误信息如下：

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/specification.rb:1206:in `block in activate_dependencies': can't satisfy 'highline (~> 1.6.11)', already activated 'highline-1.7.1' (Gem::LoadError)
    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/specification.rb:1198:in `each'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/specification.rb:1198:in `activate_dependencies'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/specification.rb:1180:in `activate'
    from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_gem.rb:48:in `gem'
    from /usr/bin/rhc:22:in `<main>'

谁能帮我解决这个问题，让我正确设置 RHC？
