运行grunt插件时出错grunt-contrib-cssmin

Question

Grunt新手在这里。我在运行grunt任务grunt-contrib-cssmin时收到以下错误。该Modernizr的任务似乎是工作：

Running "cssmin:target" (cssmin) task 
Warning: pattern.indexOf is not a function Use --force to continue. 

这里是我的gruntfile.js

​​

，这里是我的package.json文件，我有咕噜-的contrib CSS的安装在项目目录

{ 
    "name": "bootstrap-wp-less", 
    "version": "1.0.0", 
    "description": "No desc", 
    "main": "index.js", 
    "scripts": { 
    "test": "test" 
    }, 
    "author": "Me", 
    "license": "ISC", 
    "devDependencies": { 
    "grunt": "^0.4.5", 
    "grunt-contrib-cssmin": "^0.14.0", 
    "grunt-modernizr-builder": "^0.1.7" 
    } 
} 

Answer 1

我的错误是在cssmin任务，改为：

cssmin: { 
      /*options: { 
      shorthandCompacting: false, 
      roundingPrecision: -1 
      },*/ 
      target: { 
      files: { 
       'css/min/bigvideo.min.css': ['css/bigvideo.css'] 
      } 
      } 
     },
