javascript - 咕噜 imagemin 错误 : Cannot read property 'contents' of undefined

Question

当我尝试运行 Grunt imagemin 时抛出以下错误:

Running "imagemin:dynamic" (imagemin) task
Fatal error: Cannot read property 'contents' of undefined

这是我的 package.json 文件:

{
  "name": "project1",
  "version": "0.1.0",
  "devDependencies": {
    "grunt": "~0.4.1",
    "grunt-contrib-imagemin": "^1.0.0",
    "grunt-contrib-uglify": "^0.11.0",
    "imagemin" : "4.0.0"
  }
}

这是我的 Gruntfile.js

module.exports = function(grunt) {

    grunt.initConfig({

        pkg: grunt.file.readJSON('package.json'),

        uglify: {
          build: {
            src: 'views/js/src/main.js',
            dest: 'views/js/build/main.js'
          }
        },

        imagemin: {
          dynamic: {
            files: [{
              expand: true,
              cwd: 'views/images/src/',
              src: ['**/*.{png,jpg,gif}'],
              dest: 'views/images/build/'
            }]
          }
        }

    });

    // 3. Where we tell Grunt we plan to use this plug-in.
    grunt.loadNpmTasks('grunt-contrib-uglify');
    grunt.loadNpmTasks('grunt-contrib-imagemin');

    // 4. Where we tell Grunt what to do when we type "grunt" into the terminal.
    grunt.registerTask('default', ['uglify', 'imagemin']);

};

问题是 flagged and evidently resolved在先前版本的 imagemin 中。但商定的解决方案是将 grunt-contrib-imagemin 更新为 1.0.0 版，将 imagemin 更新为 4.0.0 版，我已经完成了，但仍然无法正常工作。

只需将 gurnt-contrib-imagemin 更新到 1.0.0 或最新版本，您可能使用的旧版本可能是 0.9.x
