ruby-debug安装错误：无法构buildgem原生扩展
我使用rails 3运行1.9.2。
我正在使用rvm。
我做了：
sudo gem install ruby-gem 并得到：
Building native extensions. This could take a while... ERROR: Error installing ruby-debug: ERROR: Failed to build gem native extension. /Users/blankman/.rvm/rubies/ruby-1.9.2-head/bin/ruby extconf.rb Can't handle 1.9.x yet *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.

UPDATE
添加：
gem'ruby-debug19'
并运行捆绑安装时，我得到：

这里的问题可能是安装脚本正在通过networking获取Ruby Header文件（构builddebugging器gem），但是对于您之后的特定补丁级别的补丁级别，找不到它们。 这是输出线上正在发生的事情

作为一种解决scheme，您可以指向您的本地rvm已经用来在您的机器上构buildruby的Ruby源代码副本。 开始…
gem install ruby-debug19 -- --with-ruby-include=$rvm_path/src/ruby-1.9.2-head/
非常感谢德克在下面的链接，帮助解决这个问题
ruby-debug gem与Ruby 1.9.2不兼容。 你需要使用gem ruby-debug19
所以改变你的Gemfile使用这个
gem 'ruby-debug19'
在您的gemfile中，将您的ruby-debug行更改为：
gem 'ruby-debug19', :require => 'ruby-debug'
我的来源是http://dirk.net/2010/04/17/ruby-debug-with-ruby-19x-and-rails-3-on-rvm/
我有一个类似的问题（编译本机扩展的问题）在防火墙后面的vpn中工作，并设置了http_proxy环境variables。 这种情况下安装程序无法检索ruby焦油文件。 我closuresvpn并取消设置http_proxyvariables，然后成功安装了gem。 我认为–with-ruby-include是一个替代scheme。
安装gem ruby-debug-base19x也由于使用cntlm代理连接问题而失败，“–with-ruby-include”没有为我工作。 在没有代理的情况下安装gem工作正常。
ruby-debug gem与Ruby 1.9.2及更高版本不兼容。 用下面的代码来replacegem'ruby-debug19'你需要使用gem ruby-debug19所以换上你的Gemfile来使用这个
gem'ruby-debug19'
对于windows，search你的ruby目录vm_core.h ，然后使用该目录作为你的包含path。 对我来说就是这样
gem install ruby-debug-base19 -- --with-ruby-include=C:\JRuby\lib\native\include\ruby-1.9.3-p392
然后我必须检查：
C:\JRuby\lib\ruby\gems\shared\gems\linecache19-0.5.12\ext\trace_nums\gem_make.out
并将ruby / ruby.h移动到上面的include目录中。
现在我有一些其他的错误，稍后修复…
