Rails错误：新项目

Question

我正在尝试在Rails中启动一个新项目，但我不断收到以下错误：

/Library/Ruby/Site/1.8/rubygems/dependency.rb:247:in `to_specs': Could not find railties (>= 0) amongst [] (Gem::LoadError)
        from /Library/Ruby/Site/1.8/rubygems/dependency.rb:256:in `to_spec'
        from /Library/Ruby/Site/1.8/rubygems.rb:1210:in `gem'
        from /usr/bin/rails:18

我该怎么做才能解决这个问题？
