winows7安装完 compass后 只要引入compass模块 就会报错

Question

winows7安装完 compass后 只要引入compass模块 就会报错，我确定我都安装好了 compass watch命令都正常 可以

@import 'compass/reset';

每次编译这句话都是错误的

cmd.exe /D /C call D:/soft_work/Ruby22-x64/bin/scss.bat --no-cache --update screen.scss:screen.css

      error screen.scss (Line 7: File to import not found or unreadable: compass/reset.)

Process finished with exit code 1

这是为什么啊
