我在生产环境中涉及图像时遇到了一个小问题。图像文件是使用imagemin生成的，我最终使用/ images / ..文件 - 这完全没问题，但我不知道如何在CoffeeScript中引用它们。特别是在我的ECO模板中，我正在使用BackboneJS。
CSS中的一切工作正常 - 指南针似乎正在处理正确的网址。但是没有帮助我可以使用（或者我不知道如何）来引用该图像网址。
这么简单：
<img src="images/draggable.png" />
在开发中工作，但不在生产中。
任何帮助都将不胜感激。
我正在使用grunt / yeoman。这是我的Gruntfile.js：

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

如果网站是从您的主机的根目录提供的：domain.com，那么您可以使用绝对网址来解决此问题：src =“/ images / image.png”。如果没有，你可能需要弄清楚它们在哪里。
实际上，问题可能是grunt-rev任务。它重命名图像并更新CSS / HTML，但可能不会在模板中进行。您可以检查插件以查看它是否支持该任务，如果没有，则对其进行修补，使其在模板中具有或不具有图像，并且可能仅将CSS中的图像作为背景图像。
