netbeans 下 ruby的运行问题

E:/NetBeans 6.0/ruby1/jruby-1.0.2/lib/ruby/1.8/pathname.rb:420:in `realpath_rec': No such file or directory - C:/Documents and Settings/cuilingjun/?? (Errno::ENOENT)
        from E:/NetBeans 6.0/ruby1/jruby-1.0.2/lib/ruby/1.8/pathname.rb:453:in `realpath'
        from E:/NetBeans 6.0/ruby1/jruby-1.0.2/lib/ruby/gems/1.8/gems/rails-1.2.5/lib/initializer.rb:543:in `set_root_path!'
        from E:/NetBeans 6.0/ruby1/jruby-1.0.2/lib/ruby/gems/1.8/gems/rails-1.2.5/lib/initializer.rb:509:in `initialize'
        from ./script/../config/boot.rb:38:in `new'
        from ./script/../config/boot.rb:38:in `run'
        from ./script/../config/boot.rb:38
        from :1:in `require'
        from :1
我建了个工程，运行不出来，错误提示是上面的内容，是环境问题还是其他什么原因啊？
