Gruntfile.js -任务“默认”未找到

Question

我正在尝试扩展构建在这里的D3日历Viz库：https://github.com/kamisama/cal-heatmap

我克隆了回购。代码使用Grunt作为构建过程，因此我已经在目录中安装了Grunt并运行了npm install。运行grunt我得到一个错误：

Warning: Task "default" not found. Use --force to continue.

我已经将grunt.js文件放入http://esprima.org/demo/validate.html中，并且返回时没有出现任何错误。我搞不懂为什么格特不在这里工作。

下面是grunt.js文件：

module.exports = function(grunt) {

    "use strict";

    var headerComment = "/*! <%= pkg.name %> v<%= pkg.version %> (<%= grunt.template.today() %>)\n" +
                " *  ---------------------------------------------\n" +
                " *  <%= pkg.description %>\n" +
                " *  <%= pkg.homepage %>\n" +

                " *  Licensed under the <%= pkg.license %> license\n" +
                " *  Copyright 2014 <%= pkg.author.name %>\n" +
                " */\n";

    // Project configuration.
    grunt.initConfig({
        pkg: grunt.file.readJSON("package.json"),
        jshint: {
            options: {

您需要定义默认任务，例如下面。

grunt.registerTask("default", [ "lint", "test", "coverage" ]);
