Ruby on rails “尝试时出错”；新铁路"；新安装后

我刚开始下载我所有的程序。我遇到了一个我不理解的问题，该问题已通过使用解决。它工作得很好

然后，我按照上的基本说明进行操作，当我到达步骤4

rails new test\u app

时，我收到了以下错误

/Users/Hansen/.rvm/rubies/ruby-2.1.3/lib/ruby/2.1.0/rubygems/dependency.rb:298:in `to_specs': Could not find 'railties' (>= 0) among 8 total gem(s) (Gem::LoadError)
