无法在Netbeans 6.9.1上为ruby 2.2.3p173安装快速调试器

Question

我正在尝试在Netbeans 6.9.1上调试rails项目（redmine）

当我点击调试项目时，我收到消息：

点击安装快速调试程序后，出现以下错误：

Building native extensions.  This could take a while...
ERROR:  Error installing ruby-debug-ide:
    ERROR: Failed to build gem native extension.

    /home/anatoly/.rvm/rubies/ruby-2.2.3/bin/ruby mkrf_conf.rb
Building native extensions.  This could take a while...

rake failed, exit code 1

Gem files will remain installed in /home/anatoly/.rvm/gems/ruby-2.2.3/gems/ruby-debug-ide-0.4.9 for inspection.
Results logged to /home/anatoly/.rvm/gems/ruby-2.2.3/extensions/x86_64-linux/2.2.0/ruby-debug-ide-0.4.9/gem_make.out

gem_make.out没有非常丰富的信息和帮助，至少对我而言：

/home/anatoly/.rvm/rubies/ruby-2.2.3/bin/ruby mkrf_conf.rb
Building native extensions.  This could take a while...

rake failed, exit code 1

我正在Ubuntu 14.04.1使用ruby 2.2.3p173和rails 4.2.4

我可能做错了什么？

Answer 1

我已手动安装ruby-debug-ide -v 0.4.33 gem并且问题已解决

gem install ruby-debug-ide -v 0.4.33

Answer 2

gem install ruby-debug-ide将自动安装ruby-debug-ide版本0.6，但netbeans 6.9.1需要版本0.4.3。

gem install ruby-debug-ide -v 0.4.33应该会成功。
