Question

我正在尝试使用Sass::Engine.new以编程方式将一些sass渲染到CSS中。我遇到了一个问题，我无法弄清楚如何让它允许@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放入文件并在顶部使用@import blueprint/reset时，我没有问题，它可以在开发模式中通过{{1 }}。但是我有一个新的用例，我需要自己渲染一些并遇到这个问题。在尝试渲染之前，我尝试添加rake assets:precompile，require 'compass'和require 'compass-rails'，但它不起作用。需要工作（在需要文件后，它表示require 'compass/rails'或true），但我的false电话中似乎仍无法使用。

在我的Gemfile中，我有：

Sass::Engine.new().render

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Reference或Documentation

中找不到任何内容

您没有提供蓝图的路径，而SASS找不到它。

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

你正试图用普通的SASS做到这一点。要解决此问题，您必须使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

Sass :: Engine.render不会导入蓝图库......为什么？
