运行"responsive_images:dev“(responsive_images)任务>>无法编译；没有找到有效的源文件

Question

我正在尝试设置咕噜，我已经下载了GraphickMagick和ImageMAgick。我的操作系统是LINUX。当我尝试运行$grunt时，我会得到以下错误：

Running "responsive_images:dev" (responsive_images) task
Unable to compile; no valid source files were found.
Unable to compile; no valid source files were found.

我的当前目录是/project-server

project-server/images/
project-server/img/
project-server/node_modules/
project-server/Gruntfile.js
project-server/package.json

Gruntfile.js

module.exports = function(grunt) {
grunt.initConfig({
responsive_images: {
  dev: {
    options: {
      engine: 'im',
      sizes: [{
        name: 'small',
        width: '30%',
        suffix: '_small',
        quality: 20
      },{
        name: 'large',
        width: '50%',
        suffix: '_large',
        quality: 40
      }]
    },
    files: [{
      expand: true,
      src: ['*.{gif,jpg,png}'],
      cwd: 'images/',
      dest: 'images/'
    }]
  }
},
});
grunt.loadNpmTasks('grunt-responsive-images');
grunt.registerTask('default', ['responsive_images']);
};

package.json

{
"name": "project-server",
"version": "0.1.0",
"devDependencies": {
"grunt": "^0.4.5",
"grunt-contrib-jshint": "~0.10.0",
"grunt-contrib-nodeunit": "~0.4.1",
"grunt-contrib-uglify": "~0.5.0",
"grunt-responsive-images": "^1.10.1"
}}

Answer 1

所以,

 src: ['*.{gif,jpg,png}'],
      cwd: 'images/',
      dest: 'images/'

注意cwd值，它说我当前的目录是/images，所以每当他试图查找src的值时，它就会在/images下搜索。但是我的文件{.png，.jpeg}不在/images下面。

然后，我所要做的就是注释cwd值。而且效果很好！
