为什么jruby在安装ruby-debug-ide时会给我这个错误？

Question

以下是错误日志，

$ jruby -S gem install ruby-debug-ide -v '0.4.16'
Building native extensions.  This could take a while...
ERROR:  Error installing ruby-debug-ide:

编辑：刚刚尝试使用ruby on rails 3（而不是JRuby），我得到了同样的错误。

Answer 1

-rubygems c:/Program Files/jruby-1.6.6/lib/ruby/gems/1.8/gems/rake-0.9.2.2/bin/rake

我认为你错过了那里的引号......这就是你得到错误的原因。
