我是 ROR 的新手，我正在尝试安装 DevKit，但我遇到了一些错误。我使用 Win7-64bit 并安装了 DevKit-mingw64-64-4.7.2-20130224-1432-sfx。我按照github中的安装。老实说，错误并不清楚，我不知道应该怎么做才能解决问题。
C:\Devkit>type config.yml
This configuration file contains the absolute path locations of all
installed Rubies to be enhanced to work with the DevKit. This config
file is generated by the 'ruby dk.rb init' step and may be modified
before running the 'ruby dk.rb install' step. To include any installed
Rubies that were not automagically discovered, simply add a line below
the triple hyphens with the absolute path to the Ruby root directory.
Example:
--
- C:/ruby19trunk
- C:/ruby192dev
--
c:/Ruby22
然后
C:\Devkit>ruby dk.rb install
[INFO] Skipping existing gem override for ' c:/Ruby22'
[WARN] Skipping existing DevKit helper library for ' c:/Ruby22'
和
C:\Devkit>gem install json --platform=ruby
