node.js - NodeJS：Error: Cannot find module 'jshint'

NodeJS的一个问题，提示如下：

Error: Cannot find module 'jshint'

其实我很奇怪的额，因为jshint是全局可用的：
test.js的内容

// 目标文件test.js的内容
/* jshint unused: true */
var a = 1;
var b = 2;
alert(b);

使用jshint测试输出：

λ jshint test.js
test.js: line 3, col 5, 'a' is defined but never used.

1 error

环境为：
Windows 7 + NodeJS + Gulp，环境变量NODE_PATH已设置。

在生成应用时，一个劲儿的提示找不到jshint模块，不知为何，哪位师兄给看看为何？
