如何为openshift设置RHC？我遇到:`不能满足'highline(〜> 1.6.11)',已经激活'highline-1.7.1'(Gem :: LoadError)

Question

我需要使用openshift来部署Web应用程序并修改数据库连接的文件,然后安装RHC.但它无法设置.我安装了rbenv,但实际上并不知道如何使用.我的mac买了一个星期.基本上,安装的软件并不多.完整的错误消息如下:

/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>'

任何人或任何人都可以帮我解决这个问题,让我正确设置RHC吗？
