我编译到生产时遇到此错误。
Sass :: SyntaxError：未定义的变量：“$ alert-padding”。
编译器工作正常，直到现在，只有在我备份styles.css.scss文件时才发生此错误。
在制作环境中我有
config.assets.precompile = ['*.js', '*.css', '*.css.erb', '*.scss']
styles.css.scss的内容
$btn-default-bg: green;
$btn-default-color: white;
$navbar-default-bg: white;
$navbar-default-border: white;
@import 'bootstrap';
html{
height:100%;
}
body {
height:100%;
padding-top: 60px;
background: rgba(0,123,91,1);
}
// @import 'bootstrap-responsive';
.navbar-header,
#bs-example-navbar-collapse-1{
background: #004835 !important;
}
.navbar-default .navbar-brand,
.navbar-default .navbar-nav>li>a{
color:#ffffff;
}
nav{
border:none !important;
}
