Rails 4：如何使用Sass映射？ [英] Rails 4: how do I use Sass Mappings?

问题描述

我试图清理一些Rails 4.1应用程序的样式。

 
 
 code>＃colors.css.scss 
 $ colors：（
red：＃330000，
blue：＃003300 
）;但是，我收到以下错误：
 
 
 
 
 
 
 
 
 $ b b 
 $ colors：（red：expected）之后的CSS无效，为：＃330000，blue ...
  
我可以使用Sass变量和mixins很好;为什么我不能使用SASS映射？
解决方案
正如@dinocarl指出， SASS的映射和列表的功能均为版本3+。我不得不升级 sass-rails  gem到版本5+，因为那个版本的gem包SASS 3+。在我升级gem版本后，像一个魅力（也有几个额外的依赖，我不得不更新）。
 
I'm trying to cleanup some of my styles for a Rails 4.1 app.  Instead of listing out every color and it's variations, I would like to create a mapping of colors/values and then generate the CSS by iterating over it.
# colors.css.scss
$colors: (
  "red": #330000,
  "blue": #003300
);
However, I get the following error from this:
Invalid CSS after "$colors: (red": expected ")", was ": #330000, blue..."
I can use Sass variables and mixins just fine; why can't I use SASS mappings as well?
解决方案
As @dinocarl kindly pointed out, the map and list features of SASS are in version 3+.  I had to upgrade sass-rails gem to version 5+ because that version of the gem packages SASS 3+.  Worked like a charm after I upgraded the gem version (also were few additional dependencies I had to update).
