'grunt'命令不做任何事情 [英] 'grunt' command doesn't do anything

问题描述

我对我的新应用程式执行了入门指南，但我遇到了一些麻烦。

这是我的Gruntfile.js

  module.exports = function（grunt） {
 
 //项目配置。 
 grunt.initConfig（{
 pkg：grunt.file.readJSON（'package.json'），
 uglify：{，
 build：{
 src： js / *。js'，
 dest：'build / *。min.js'
} 
} 
} 
 
 //加载提供uglify任务的插件。 
 grunt.loadNpmTasks（'grunt-contrib-uglify'）; 
 
 //默认任务。 
 grunt.registerTask（'default'，['uglify']）; 
 
}; 
  

这是我的package.json

  {
name：My App，
version：0.0.0，
description：，
author：，
license：N / A，
devDependencies：{
grunt：〜0.4.2，
grunt-contrib-jshint：〜0.8.0，
grunt-contrib-uglify：〜0.2.7
} 
} 
  

我安装了grunt-cli软件包，我运行了npm install来获取本地版本的grunt和contrib库。

但是当我运行 grunt 或 grunt uglify 没有任何反应。

  $ grunt 
 $ grunt uglify 
 $ 
  
 
 
编辑：我刚安装摩卡太，我得到同样的问题：没有输出。也许我的节点或npm安装有问题
解决方案
所以看起来这是一个环境安装问题。我有一个ubuntu包称为节点安装以及nodejs，这阻止通过npm安装的软件包工作。运行以下命令解决了问题。
  sudo apt-get --purge remove node 
  
 
I'm following the grunt getting started guide for my new app, but I'm having some trouble.

This is my Gruntfile.js
module.exports = function(grunt) {

  // Project configuration.
  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
    uglify: {,
      build: {
        src: 'js/*.js',
        dest: 'build/*.min.js'
      }
    }
  });

  // Load the plugin that provides the "uglify" task.
  grunt.loadNpmTasks('grunt-contrib-uglify');

  // Default task(s).
  grunt.registerTask('default', ['uglify']);

};
This is my package.json
{
  "name": "My App",
  "version": "0.0.0",
  "description": "",
  "author": "",
  "license": "N/A",
  "devDependencies": {
    "grunt": "~0.4.2",
    "grunt-contrib-jshint": "~0.8.0",
    "grunt-contrib-uglify": "~0.2.7"
  }
}
I have the grunt-cli package installed and I've run npm install to get a local version of grunt and the contrib libraries.

But when I run either grunt or grunt uglify nothing happens.
$ grunt
$ grunt uglify
$
Any idea what I have missed or what could cause this behaviour?

EDIT: I just installed mocha too and I get the same issue with that: no output. Maybe there is a problem with my node or npm installation
解决方案
So it looks like this was an environment setup issue. I had an ubuntu package called node installed as well as nodejs which was preventing the packages installed through npm from working. Running the following command fixed the issue.
sudo apt-get --purge remove node
