C:\DevKit>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.
我的 ruby 安装在 C 盘， C:\Ruby200-x64>ruby -v ruby 2.0.0p247 (2013-06-27) [x64-mingw32]
我在家的电脑上也遇到这个问题， 安装顺序是先安装 ruby 后安装的 Devkit，参照这个页面，始终不行，https://github.com/oneclick/rubyinstaller/wiki/Development-Kit 现在找不到问题点在哪里 请帮忙看一下
Run Installation Scripts
cd from Step 3 above.
ruby dk.rb init to generate the config.yml file to be used later in this Step. Your installed Rubies will be listed there (only those installed by a RubyInstaller package are detected at present).
edit the generated config.yml file to include installed Rubies not automatically discovered or remove Rubies you do not want to use the DevKit with.
[optional] ruby dk.rb review to review the list of Rubies to be enhanced to use the DevKit and verify the changes you made to it are correct.
finally, ruby dk.rb install to DevKit enhance your installed Rubies. This step installs (or updates) an operating_system.rb file into the relevant directory needed to implement a RubyGems pre_install hook and a devkit.rb helper library file into \lib\ruby\site_ruby. NOTE: you may need to use the --force option to update (with backup of the originals) the above mentioned files as discussed at the SFX DevKit upgrade FAQ entry.
If you use the x64 version of ruby you might get an error saying Invalid configuration. Please fix ‘config.yml’ and rerun ‘ruby dk.rb install’. See http://stackoverflow.com/questions/16523607/cant-get-ruby-devkit-configuration-file-autogenerated-properlyni 你还没有安装完毕呢，有什么问题吗
你现在只是
ruby dk.rb init
然后在
ruby dk.rb review
看看有没有找到你的 ruby 路径， 找到了在
ruby dk.rb install
