这是一个棘手的问题需要解释，我会尽可能彻底地尝试：
我按照Zurb的说明，以最基本的方式（仅使用Sass文件）将Jekyllrb Yeoman generator和Zurb的基础5集成到其中。
grunt.js 中的我的Sass路径如下：
loadPath: 'app/_bower_components/foundation/scss'
在我的/ _scss中我有：
app.scss
_settings.scss
在app.scss中 - 我包括许多基础组件（例如手风琴，类型，标签等）。每个人都带来一套全球风格。这些样式包含在以下内容中：
@include exports("global") { ... }
根据this link：
＆＃34;当包含在SASS模块中时，如果在其他地方调用@import，sass-import-once将阻止样式重复。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，并允许模块在需要时独立。＆＃34;

这些全局样式在最终编译的样式表中被复制，无论＆＃39; @include导出＆＃39;函数告诉它解决重复。我之前使用过grunt-contrib-sass而且从未遇到过这个问题。引导我去思考其他一些任务可能会导致它吗？
我知道Foundation的_settings.scss中有一个变量，它有：
$include-html-global-classes: $include-html-classes;
我不希望关闭它 - 因为我 做 想要我的样式表中的全局样式 - 我只是希望它们出现一次。
我会非常感激如果有人能为我看看这个。我已经汇总了一个最基本的例子来说明这个问题。快速查看检查器（在提供页面时）将向您显示DOM中重复样式的混乱。
答案 0 :(得分：8)
根据基金会GitHub上的this issue，基金会快速行动并打破exports行为，这有点麻烦。
我尝试将您的测试存储库与Foundation回滚到版本5.4.4（而不是最新的，5.4.5），这对我有用。
因此，您只需将bower.json中的基金会依赖关系更改为：
"dependencies": {
"foundation": "zurb/bower-foundation#5.4.4"
},
从我在该问题主题中读到的内容，一旦Foundation发布5.5，您应该可以毫无问题地切换到该问题。
希望有所帮助！
