我找到此资源： http://www.clausconrad.com/blog/installing-caldecott-on-wwords  
 

这是有帮助的，但我的问题是我在我的系统上安装了多个ruby。 
 

因此，请确保您使用正确的ruby安装，并删除其他如果需要：
i has：
 

 C：/ Program Files / ruby​​-1.9。 2 / bin / ruby​​.exe 
 

和
 

 C：\Ruby193\bin\ruby。 exe 
 

我删除了第一个，一切都很好，一定要安装devkit像链接说，一切都应该好。

i found this resource  : http://www.clausconrad.com/blog/installing-caldecott-on-windows

which was helpfull but my problem was i had multiple ruby installations on my system !

so make sure you are using the right ruby installation and delete the others if needed :
i had :

C:/Program Files/ruby-1.9.2/bin/ruby.exe

and 

C:\Ruby193\bin\ruby.exe

i deleted the first one and everything went fine , be sure to install the devkit like the link says , and everything should be allright.
