1.在 E:\RailsInstaller\DevKit 目录下，进入命令行输入：ruby dk.rb init 提示：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. 此时：config.yml 文件配置信息没有自动生成 ruby 安装路径，文件中全部是注释信息

2.手动在 config.yml 文件中加上路径：

• E:/RailsInstaller/Ruby2.0.0，之后进入命令行输入：ruby dk.rb install 提示：[INFO] Skipping existing gem override for 'E:/RailsInstaller/Ruby2.0.0' [WARN] Skipping existing DevKit helper library for 'E:/RailsInstaller/Ruby2.0.0'

有人知道是什么情况吗
