ruby-on-rails - ruby-debug安装错误: failed to build gem native extension

Question

我正在使用 Rails 3 运行 1.9.2。

我正在使用rvm。

我做到了:

sudo gem install ruby-gem

得到:

Building native extensions.  This could take a while...
ERROR:  Error installing ruby-debug:

更新

添加:

gem 'ruby-debug19'

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)，但找不到您想要的特定 Ruby 补丁级别的文件。这就是输出行中发生的事情

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​​。这里...

gem install ruby-debug19 -- --with-ruby-include=$rvm_path/src/ruby-1.9.2-head/
