我正在尝试使用SASS编译Foundation。不幸的是有些错误，因为我只获得了预期的.css文件的一部分。
我正在使用：
sass foundation.scss foundation.css
我的foundation.scss看起来像：
@charset "UTF-8";
// Foundation by ZURB
// foundation.zurb.com
// Licensed under MIT Open Source
// Make sure the charset is set appropriately
// Behold, here are all the Foundation components.
@import "foundation/components/grid";
@import "foundation/components/accordion";
@import "foundation/components/alert-boxes";
@import "foundation/components/block-grid";
@import "foundation/components/breadcrumbs";
@import "foundation/components/button-groups";
@import "foundation/components/buttons";
@import "foundation/components/clearing";
@import "foundation/components/dropdown";
@import "foundation/components/dropdown-buttons";
@import "foundation/components/flex-video";
@import "foundation/components/forms";
@import "foundation/components/icon-bar";
@import "foundation/components/inline-lists";
@import "foundation/components/joyride";
@import "foundation/components/keystrokes";
@import "foundation/components/labels";
@import "foundation/components/magellan";
@import "foundation/components/orbit";
@import "foundation/components/pagination";
@import "foundation/components/panels";
@import "foundation/components/pricing-tables";
@import "foundation/components/progress-bars";
@import "foundation/components/range-slider";
@import "foundation/components/reveal";
@import "foundation/components/side-nav";
@import "foundation/components/split-buttons";
@import "foundation/components/sub-nav";
@import "foundation/components/switches";
@import "foundation/components/tables";
@import "foundation/components/tabs";
@import "foundation/components/thumbs";
@import "foundation/components/tooltips";
@import "foundation/components/top-bar";
@import "foundation/components/type";
@import "foundation/components/offcanvas";
@import "foundation/components/visibility";
看起来，我的SAAS只编译那些导入：
@import "foundation/components/icon-bar";
@import "foundation/components/visibility";
我不知道问题出在哪里。所有文件都是原创文件，不予修改。
