Question

问题是我无法将.css文件最小化到dist文件夹中。当我运行命令'grunt'时，我收到以下错误。帮我。提前谢谢。

Running "concat:dist" (concat) task

Running "cssmin:dist" (cssmin) task
>> No files created.

Running "uglify:dist" (uglify) task
>> No files created.

Running "copy:dist" (copy) task


Running "copy:fonts" (copy) task

我的HTML文件头和Grunt.js的代码如下：

'use strict';

module.exports = function (grunt) {
  // Define the configuration for all the tasks
    	// Time how long tasks take. Can help when optimizing build times
  	require('time-grunt')(grunt);

  	// Automatically load required Grunt tasks
  	require('jit-grunt')(grunt, {
  	  useminPrepare: 'grunt-usemin'
  	}); 
  	// Define the configuration for all the tasks
  	grunt.initConfig({
  	  pkg: grunt.file.readJSON('package.json'),

  	  // Make sure code styles are up to par and there are no obvious mistakes
  	  jshint: {
  	    options: {

  	  },
  	  copy: {

  	// Usemin

您的cssmin:是空的！

您需要执行以下操作：

 cssmin: {
  target: {
    files: [{
      expand: true,
      cwd: 'release/css',
      src: ['dist/styles/*.css', '!*.min.css'],
      dest: 'release/css',
      ext: '.min.css'
    }]
  }
}
