我的scss代码是

@import "compass";
@import "spr/*.png";
 h1 { @include spr-sprite("car");  height:50px; width:50px; }

我的css输出为精灵

.spr-sprite,h1 {  background: url('/images/spr-sa37328aec0.png') no-repeat; }
h1 {  background-position: 0 -147px;  
height: 50px; 
width: 50px;
overflow: hidden; 
text-align: left; 

                  }

你可以看到背景不应该以../开头,而不是直接用/ images /开头.它造成了一个问题.
我的图像文件夹路径

images
 ------spr
          ---*.png
sass
-----screen.scss
css
---screen.css

我的config.rb代码

# Require any additional compass plugins here.
# Set this to the root of your project when deployed:
http_path = "/"
css_dir = "stylesheets"
sass_dir = "sass"
images_dir = "images"
javascripts_dir = "javascripts"

我是sass和指南针的新手,所以可能我错过了一些代码.请帮我找出来.
任何帮助将不胜感激.非常感谢提前回复.
