Grunt文件执行错误找不到任务服务

Question

Grunt文件未由命令grunt服务执行。这是我的文件。

(function (module) {
  'use strict';

  module.exports = function (grunt) {
    // These variable would be passed in from the master build file.
    var target = grunt.option('target') || 'staging',
        version = grunt.option('product_version') || 'version_not_set';

我已经通过所有的需要命令安装了grunt。当我要运行这个文件时，命令给出了错误：- taks serve not found。使用--force继续..
