我是Rails的新手，我使用sass-bootstrap gem在我的Rails项目中使用bootstrap。一切都加载速度相当快，但现在每次更改任何scss文件时，预编译时间最多需要90秒才能完成。
在application.css.scss中，我在顶部导入bootstrap并根据其他建议要求partials，并将config.assets.debug设置为false;
这是我的application.css.scss
@import "bootstrap";
/*
* This is a manifest file that'll be compiled into application.css, which will include all the files
* listed below.
*
* Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
* or any plugin's vendor/assets/stylesheets directory can be referenced here using a relative path.
*
* You're free to add application-wide styles to this file and they'll appear at the bottom of the
* compiled file so the styles you add here take precedence over styles defined in any styles
* defined in the other CSS/SCSS files in this directory. It is generally better to create a new
* file per style scope.
*
*= require _static_pages
*= require_tree .
*= require_self
*/
还有什么我可能做得不对，导致如此痛苦的加载时间？ 我已经看到其他类似的问题类似，但似乎没有一个适合我的Bootstrap情况或提供有效的答案。
