模糊版本问题：
- 如何在 grunt 规范中使用 require ？
Context:
我正在开发一个尚未测试的现有节点项目，所以我阅读了一些内容并意识到使用 karma 和 jasmine。
我读了一些教程（包括这些）：
- http://kwilson.me.uk/blog/use-karma-and-grunt-to-run-your-jasmine-tests-in-real-time/ http://kwilson.me.uk/blog/use-karma-and-grunt-to-run-your-jasmine-tests-in-real-time/
- http://ahexamples.blogspot.com.br/2014/03/example-of-jasmine-karma-sonar-grunt.html http://ahexamples.blogspot.com.br/2014/03/example-of-jasmine-karma-sonar-grunt.html
所以我尝试用 grunt 运行我的规范并收到此错误：
X遇到声明异常
ReferenceError：找不到变量：在 file:///(...)-spec.js 中需要（第 2 行）(1)
该行是这样的：
var myHelper = require(...);
但如果我通过终端“node-jasmine test”使用它就像一个魅力......
我的项目结构：
- 控制器/
- helpers/
- models/
- 节点模块/
- 资源/
- test/
- 测试/规格/
- views/
- app.js
- Gruntfile.js
- 包.json
在我的规范（在 test/spec/ 内）中，我使用了 require('../../helpers/helper.js') ，这对于 node-jasmine 来说没问题，但对于 grunt 来说不行。
节点茉莉花测试：
.....
在 0.015 秒内完成 5 次测试，5 次断言，0 次失败，0 次跳过
grunt:
运行“jasmine:pivotal”（茉莉花）任务通过测试茉莉花规格
PhantomJS
ReferenceError：找不到变量：需要在
app.js:1 Service Helper Tests X 遇到声明异常
ReferenceError：找不到变量：在文件中需要：:///(...)/test/spec/serviceHelper-spec.js
（第 2 行）(1)
0.005 秒内 1 个规格。
1 次失败警告：任务“jasmine:pivotal”失败。使用 --force 继续。
由于警告而中止。
我已将所有包安装到 node_modules 中（package.json 中的依赖项中没有任何内容），我的 Gruntfile.js 是：
