Ruby on rails Rails 4资产编译在开发模式下非常慢（>；1分钟）。如何排除故障？

我正在使用Rails 4应用程序和引导。在某个时候，资产编译被破坏了，现在如果我对SCSS文件进行任何更改，重新加载一个页面需要一分钟。更改JS文件不会导致此延迟。我不知道是什么导致了这种情况，但当我试图自己预先编译这些资产时，这个过程大约需要2秒钟才能完成。不知道为什么在飞行中发生这种情况需要一分钟，有时超过2分钟

我在livereload中使用guard，当我在样式表中保存更改时，页面是livereloaded的，但没有任何样式表。如果我重新加载页面，则渲染需要一分钟。我希望有一些明显的东西我只是错过了，有人发现它

在进行故障排除时，我切换了配置，以便将scss文件加载到application.css.scss（使用

*=require

语法）中，然后在每个文件中导入引导变量和mixin，但速度同样慢。我还尝试使用CDN引导，然后过度编写，但速度也几乎一样慢，覆盖这么多类让人头疼

延迟发生在布局的呈现过程中，但只有在我更改样式表时才会发生。任何其他更改，它几乎立即加载

我有一大堆的设计/css工作要做，这几乎是不可能的。请帮忙

（可能还有一些其他文件我也应该在这里发布。请告诉我，我会发布的。）

还有什么我可以补充的吗？或者运行任何测试？

根据我的经验，

/=require

比开发环境中的

@import

要快，但在某些情况下可能会很麻烦

是的，我改用了大部分//=require，但它似乎根本没有加快速度（可能是70秒，而不是80秒……大喘息），所以我把它放回去了。
