我正在尝试将 grunt 任务的执行包装在另一个节点脚本中（用于构建简单的集成），并且在让所有任务运行时遇到问题。这是我非常简单的测试脚本：
'use strict';
var path = require('path');
var g = require('grunt');
g.tasks();
这是输出：
-> % node test.js
Running "jshint:all" (jshint) task
>> 50 files lint free.
Running "clean:server" (clean) task
Running "concurrent:test" (concurrent) task
该进程卡在并发任务上，并将 cpu 固定在 100%。它似乎对任何并发任务都这样做。如果它跳过 :test 任务，它稍后会在另一个任务中失败，并使用 compass 和其他一些东西。
test.js 与我的 Gruntfile.js 位于同一目录中。如果我只运行“咕噜”，它会很好地完成整个过程。

解决方法：如果我将并发分组中的任务分别在 registerTask 下列出，则该过程可以正常工作。
