grunt 新手 - 警告：找不到任务 "concat, uglify"

Question

正如标题所说，我是 G运行t 的新手。我正在关注位于 http://24ways.org/2013/grunt-is-not-weird-and-hard/ 的教程。这是一个较旧的教程，但大多数似乎都一样。我已经安装了 "grunt-contrib-concat" 和 "grunt-contrib-uglify"，并且可以单独安装运行。但是当我运行 grunt 时，我得到以下错误： Warning: Task "concat, uglify" not found. Use --force to continue. Aborted due to errors. 我一直在四处寻找，似乎无法弄清楚。我的文件如下：

Gruntfile.js:

module.exports = function(grunt) {

            // 1. All configuration goes here 
            grunt.initConfig({
                pkg: grunt.file.readJSON('package.json'),

                concat: {

                    dist: {
                        src: [
                            'js/libs/*.js', // All JS in the libs folder
                            'js/controls.js', // This specific file
                        ],
                        dest: 'dist/built.js',
                    }
                },

                uglify: {
                    build: {
                        src: 'js/build/production.js',
                        dest: 'js/build/production.min.js',
                    }
                },

            });

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

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

        };

package.json:

{
  "name": "grunt_libsass_example-project",
  "version": "0.1.0",
  "devDependencies": {
    "grunt": "~0.4.1",
    "grunt-contrib-concat": "^0.5.1",
    "grunt-contrib-uglify": "^0.9.1"
  }
}

Answer 1

您只为 registerTask 任务列表传入了一个字符串。它应该是逗号分隔的字符串列表，例如：

grunt.registerTask('default', ['concat', 'uglify']);

您收到该错误是因为它正在寻找名为 'concat, uglify' 的任务。
