我正在使用 Rails 3 运行 1.9.2。
我正在使用rvm。
I did:
sudo gem install ruby-gem
and got:
Building native extensions. This could take a while...
ERROR: Error installing ruby-debug:
ERROR: Failed to build gem native extension.

当运行捆绑安装时我得到：

这里的问题可能是安装脚本将通过网络获取 Ruby 头文件（以构建调试器 gem），但找不到您所需要的特定 Ruby 补丁级别的文件。这就是输出行中发生的情况
Looking for http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.2-p14.tar.gz and all I got was a 404! (URI::NotFoundError)
作为解决方案，您可以指向 Ruby 源的本地副本，rvm 已使用该副本在您的计算机上构建 ruby。开始...
gem install ruby-debug19 -- --with-ruby-include=$rvm_path/src/ruby-1.9.2-head/
非常感谢 Dirk 在以下链接中帮助解决了这个问题
