我正在尝试使用Sass::Engine.new. 我遇到了一个问题，我不知道如何让它允许@import GEMMIFIED_SASS_MODULE。例如，这就是我正在尝试的：

?> sass = "@import \"blueprint/reset\"\nh1\n  width: 100%"
=> "@import \"blueprint/reset\"\nh1\n  width: 100%"
>> puts sass # For readable version
@import "blueprint/reset"
h1
  width: 100%
=> nil
>> Sass::Engine.new(sass, :syntax => :sass).render
Sass::SyntaxError: File to import not found or unreadable: blueprint/reset.

当我将一些 sass 放入文件并@import blueprint/reset在顶部使用时，这样做没有问题，它能够在开发模式和 via 中即时编译为 CSS rake assets:precompile。但是我有一个新的用例，我需要自己渲染一些并且遇到了这个问题。在尝试渲染它之前，我尝试添加require 'compass',require 'compass-rails'和require 'compass/rails'，但它不起作用。需要工作（因为它说true或在需要文件之后），但在我的通话false中似乎仍然不可用。Sass::Engine.new().render

在我的 Gemfile 中，我有：

gem 'haml-rails'
gem 'sass-rails'
gem 'compass-rails'

任何人都知道在使用 Sass::Engine 时我可以做些什么来使库可见？我在参考或文档中找不到任何内容

您没有提供蓝图的路径，SASS 找不到它。

Compass 是为解决此问题而创建的工具。它提供了一个可以直接导入而无需提供路径的扩展生态系统。

你正试图用普通的 SASS 来做到这一点。要解决此问题，您必须让 SASS 熟悉 Compass 扩展的存储位置： 

# Allowing vanilla SASS use Compass extensions
Compass.sass_engine_options[:load_paths].each do |path|
  Sass.load_paths << path
end
