@if compass-env() == 'development' {
    @import 'debug'; #导入样式表
}

改为：

@if compass-env() == 'development' {
    body {
        color: red; #改为内置样式表
    }
}

测试环境 Sass 3.2.5 + Compass 0.12.2 + Ruby 1.9.3p194.

全局安装gulp-sass后仍然提示gulp 未安装 目前原因不明， 路径设置也设置了全局路径， 依然不生效，只好在本地再次安装 package.json包 npm install --save-dev
