如何在Win7上调试Ruby程序

先安装rubyinstaller，下载并解压DevKit，注意，这两个版本要对应，网页上有说明（http://rubyinstaller.org/downloads/），解压DevKit后，打开目录，运行devkitvars.bat（是不是必须的不确定）。

打开cmd，进入DevKit的解压目录

ruby dk.rb

---

Configures an MSYS/MinGW based Development Kit (DevKit) for
each of the Ruby installations on your Windows system. The
DevKit enables you to build many of the available native
RubyGems that don't yet have a binary gem.

Usage: ruby dk.rb COMMAND [options]

where COMMAND is one of:

  init     prepare DevKit for installation
  review   review DevKit install plan
  install  install required DevKit executables

and 'install' [options] are:

  -f, --force  overwrite existing helper scripts

-------------

ruby dk.rb init

---

Initialization complete! Please review and modify the auto-generated
'config.yml' file to ensure it contains the root directories to all
of the installed Rubies you want enhanced by the DevKit.

--------------------------------

ruby dk.rb install

---

Invalid configuration or no Rubies listed. Please fix 'config.yml'
and rerun 'ruby dk.rb install'
如果出现的是这个，则需要修改config.yml

加入

- C:\Ruby200-x64

---
[INFO] Updating convenience notice gem override for 'C:/Ruby200-x64'
[INFO] Installing 'C:/Ruby200-x64/lib/ruby/site_ruby/devkit.rb'

这是对的

---------------------

gem install ruby-debug-ide

---

Temporarily enhancing PATH to include DevKit...

-------------------------

安装aptana 的eclipse plugin ，url http://download.aptana.com/studio3/plugin/install

这样就能调试ruby程序了
