ruby-on-rails – debugger-linecache安装错误

我尝试安装debugger-linecache gem,但是我收到以下错误,

Building native extensions.  This Could take a while...
....
ERROR:  Error installing debugger-linecache:
        ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason,probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more

Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/debugger-linecache-1.1.1 for inspection.

我已经完成了：

sudo gem install debugger-ruby_core_source

解决方法

我发现问题是,因为我在fedora,我使用ruby 1.8.3,这似乎是问题.现在升级到ruby 1.9.3,问题解决了.
