ActiveSupport 无法在 Rails 2.3.4 下加载 Sass 引擎
我正在尝试在控制器中使用 Sass 引擎，如这篇博客文章中所示。但是 Rails (2.3.4) ActiveSupport 由于错误而无法加载它：
ArgumentError (Anonymous modules have no name to be referenced by):
haml (3.0.25) lib/sass/script/color.rb:19
haml (3.0.25) lib/sass/script/literal.rb:10
haml (3.0.25) lib/sass/script/string.rb:1
haml (3.0.25) lib/sass/script/operation.rb:2
haml (3.0.25) lib/sass/script.rb:5
haml (3.0.25) lib/sass/engine.rb:22
app/controllers/stylesheets_controller.rb:1
这是 Sass::Script::Color 中的代码
class << self; include Haml::Util; end
我已经尝试过最新的 Haml 版本和 2.2 版本。 24 具有相同的结果。有兼容版本吗？是我这边有问题吗？
I'm trying to use Sass engine in a controller like in this blog post. But Rails (2.3.4) ActiveSupport can't load it because of an error:

haml (3.0.25) lib/sass/script.rb:5
haml (3.0.25) lib/sass/engine.rb:22
app/controllers/stylesheets_controller.rb:1
Here's the code in Sass::Script::Color
class << self; include Haml::Util; end
I've tried with the latest Haml version and also version 2.2.24 with the same result. Is there a compatible version? Is there a problem on my side?

最后，这很愚蠢，
Sass::Script::Color文件不需要Haml::Util，所以我必须自己做：Finally it was quite stupid, the
Sass::Script::Colorfile wasn't requiringHaml::Util, so I had to do it myself:
