无法运行 Grunt 任务

Question

我在运行时的大多数 Grunt 任务都面临着类似的问题。请帮助解决这个问题。

在下面添加命令提示符命令，gruntFile.js 和 package.json 文件

grunt 复制 --force

SyntaxError: Unexpected identifier 警告：找不到任务“副本”。使用 --force，继续。

咕噜咕噜的丑化

SyntaxError：意外标识符警告：找不到任务“uglify”。使用 --force 继续。

GruntFile.js

'use strict';

module.exports = function (grunt) {

    // https://github.com/sindresorhus/load-grunt-tasks
    require('load-grunt-tasks')(grunt);

    // http://gruntjs.com/configuring-tasks#grunt-configuration
    grunt.initConfig({

从您的package.json，您尚未下载uglify 任务。

npm install grunt-contrib-uglify --save-dev
