我在生产环境中遇到了一个关于图像的小问题。图像文件是使用 imagemin 生成的，我最终得到 /images/.. 文件——这完全没问题，但我不知道如何在 CoffeeScript 中引用它们。特别是在我使用 BackboneJS 的 ECO 模板中。
在 CSS 中一切正常—— compass 似乎在处理正确的 url。但是没有帮助我可以使用（或者我不知道如何）来引用该图像 url。
所以一个简单的：
<img src="images/draggable.png" />
在开发中工作，但不在生产中。
任何帮助，将不胜感激。
我正在使用 grunt/yeoman。这是我的 Gruntfile.js：
'use strict';
if (process.env.NODE_ENV != 'production') {
var LIVERELOAD_PORT = 35729;
var lrSnippet = require('connect-livereload')({port: LIVERELOAD_PORT});
var mountFolder = function (connect, dir) {
return connect.static(require('path').resolve(dir));
};
}
// # Globbing
// for performance reasons we're only matching one level down:
// 'test/spec/{,*/}*.js'
// use this if you want to match all subfolders:
// 'test/spec/**/*.js'
// templateFramework: 'lodash'
module.exports = function (grunt) {
// load all grunt tasks
require('matchdep').filterDev('grunt-*').forEach(grunt.loadNpmTasks);
// configurable paths
