gruntjs – 供应商css,在concat和minify之后没有图像

我在角项目中使用select2(使用yeoman). Select2 css位于以下目录中：

bower_components / SELECT2 / select2.css
bower_components / SELECT2 / select2.png

css以下列方式使用select2.png：background-image：url(‘select2x2.png’)

运行concat并缩小后,我有以下结构：

bower_components / SELECT2 / d204997b.select2x2
款式/ 034d1972.vendor.css

但问题是venodr css的select2部分正在寻找样式目录中的d204997b.select2x2.

这是我的GruntJS文件的一部分：

rev: {
      dist: {
        files: {
          src: [
            '<%= yeoman.dist %>/scripts/{,*/}*.js',
            '<%= yeoman.dist %>/styles/{,*/}*.css',
            '<%= yeoman.dist %>/images/{,*/}*.{png,jpg,jpeg,gif,webp,svg}',
            '<%= yeoman.dist %>/bower_components/select2/{,*/}*.{png,jpg,jpeg,gif,webp,svg}',
            '<%= yeoman.dist %>/styles/fonts/*'
          ]
        }
      }
    },
useminPrepare: {
  html: '<%= yeoman.app %>/index.html',
  options: {
    dest: '<%= yeoman.dist %>'
  }
},

usemin: {
  html: ['<%= yeoman.dist %>/{,*/}*.html'],
  css: ['<%= yeoman.dist %>/styles/{,*/}*.css'],
  options: {
    assetsDirs: ['<%= yeoman.dist %>' ,'<%= yeoman.dist %>/images' , '<%= yeoman.dist %>/bower_components/select2']
  }
}

谢谢

我找不到一个很好的方法来做到这一点.我所做的是使用grunt任务grunt-replace来修复所有css图像路径.

笨拙的任务

/**
 * Replaces image paths in CSS to match ../img. Select2 is the only css file this is needed for so far.
 * Others can be added.
 */
replace: {
    build: {
        src: ['<%= build %>/assets/lib/css/select2.css'],
        overwrite: true,
        replacements: [
            {
                from: /url\('(?!\.)/g,
                to: 'url(\'../img/'
            },
            {
                from: /url\((?!\')/g,
                to: 'url(\'../img/'
            },
            {
                from: /..\/images\//g,
                to: '../img/'
            },
            {
                from: /(png|gif|jpg)(?=\))/g,
                to: '$1\''
            }
        ]
    }
}

我还将所有select2图像复制到文件夹“img”中.只要任务“to：”匹配,那部分就可以是你想要的任何东西.
