这是一个很难解释的问题，我会尽量做到彻底：
我的设置 - 使用 Jekyllrb 生成器
根据 Zurb 的说明，我采用了Jekyllrb Yeoman 生成器并以最基本的方式（仅使用 Sass 文件）将 Zurb 的 Foundation 5 集成到其中。
我在grunt.js中的 Sass 路径如下：
loadPath: 'app/_bower_components/foundation/scss'
在我的 /_scss 我有：
app.scss
_settings.scss
在 app.scss - 我包含了一些 Foundation 组件（例如手风琴、类型、选项卡等）。每一个都带来了一套全球风格。这些样式包含在以下内容中：
@include exports("global") { ... }
根据此链接：
“当包含在 SASS 模块中时，sass-import-once 将防止在其他地方调用 @import 时重复样式。这很酷，因为它允许每个 SASS 文件声明自己的依赖项。这促进了封装并允许模块独立如果需要的话。”

问题
这些全局样式在最终编译的样式表中被复制，而不管“@include 导出”函数是否告诉它解析重复项。我以前使用过 grunt-contrib-sass 并且从未遇到过这个问题。导致我认为其他任务可能导致它？
关于更多的事情：
我知道 Foundation 的 _settings.scss 中有一个变量：
$include-html-global-classes: $include-html-classes;
我不想关闭它——因为我确实想要样式表中的全局样式——我只希望它们出现一次。
我已经设置了一个回购
如果有人能帮我看看这个，我将非常感激。我整理了一个最基本的例子来说明这个问题。快速查看检查器（在为页面提供服务时）将向您展示 DOM 中重复的样式。
