错误编译CSS资产指南针

Question

你好我试图用罗盘按照下进行转换，但我得到一个编译错误，指出“未定义混入背景图片”

#header_toolbar { 
height: 40px; 
/* The black toolbar gradient :) */ 
background: #313131; /* Old browsers */ 
@include background-image(linear-gradient(left top, #313131, #101010)); 
/*background: -moz-linear-gradient(top, #313131 0%, #101010 100%); *//* FF3.6+ *//* 
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#313131), color-stop(100%,#101010)); *//* Chrome,Safari4+ *//* 
background: -webkit-linear-gradient(top, #313131 0%,#101010 100%); *//* Chrome10+,Safari5.1+ *//* 
background: -o-linear-gradient(top, #313131 0%,#101010 100%); *//* Opera 11.10+ *//* 
background: -ms-linear-gradient(top, #313131 0%,#101010 100%); *//* IE10+ *//* 
background: linear-gradient(top, #313131 0%,#101010 100%); *//* W3C */ 
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#313131', endColorstr='#101010',GradientType=0); /* IE6-9 */ 

}

的Gemfile

# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails', '~> 3.2.3' 
    gem 'coffee-rails', '~> 3.2.1' 

    # See https://github.com/sstephenson/execjs#readme for more supported runtimes 
    # gem 'therubyracer', :platform => :ruby 

    gem 'uglifier', '>= 1.0.3' 
    gem 'compass-rails' 
    gem "compass", "~> 0.12.1" 
end

您需要导入混入你的SCSS：

@import "compass/css3/images"

看看这里了解让你在一个地方进口，而不是在每一个SCSS文件中定义他们的想法：http://compass-style.org/help/tutorials/best_practices/
