新的grunt - 警告：任务“concat，uglify”未找到 [英] new to grunt - warning: task "concat, uglify" not found

问题描述

正如标题所说，我是Grunt的新手。我正在学习以下教程： http://24ways.org/ 2013 /咕噜 - 是 - 不奇怪的和硬/ 。这是一个较老的教程，但大多数似乎工作相同。我已经安装了grunt-contrib-concat和grunt-contrib-uglify，可以单独运行。但是当我运行 grunt 时，出现以下错误：警告：未找到任务concat，uglify。使用--force继续。因错误而中止。我一直在环顾四周，似乎无法弄清楚。我的文件如下：

Gruntfile.js：

 模块.exports = function（grunt）{
 
 // 1.所有配置都在这里
 grunt.initConfig（{
 pkg：grunt.file.readJSON（'package.json' ），
 
 concat：{
 
 dist：{
 src：[
'js / libs / *。js'，// All JS in libs文件夹
'js / controls.js'，//这个特定文件
]，
 dest：'dist / built.js'，
} 
} ，
 
 uglify：{
 build：{
 src：'js / build / production.js'，
 dest：'js / build / production.min。 js'，
} 
}，
 
}）; 
 
 // 3.我们告诉Grunt我们打算使用这个插件。 
 grunt.loadNpmTasks（'grunt-contrib-concat'）; 
 grunt.loadNpmTasks（'grunt-contrib-uglify'）; 
 
 // 4.当我们在终端输入'grunt'时告诉Grunt该做什么。 
 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
} 
} 
  

解决方案

registerTask任务列表的一个字符串。它应该是逗号分隔的字符串列表，如：

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

你正在寻找一个名为'concat，uglify'的任务。 p>

As the title says I'm new to Grunt. I am following a tutorial located at: http://24ways.org/2013/grunt-is-not-weird-and-hard/. It is an older tutorial but most seems to work the same. I have installed "grunt-contrib-concat" and "grunt-contrib-uglify" and can run both individually. But when I run grunt, I get the following error: Warning: Task "concat, uglify" not found. Use --force to continue. Aborted due to errors. I've been looking around and can't seem to figure it out. My files are as follows:

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"
  }
}

解决方案

Your passing in only one string for the registerTask task list. It should be a comma separated list of strings like:

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

You're getting that error because it's looking for a task named 'concat, uglify'.
