所以我正在尝试使用用 CoffeeScript 编写的 Mocha 和 Chai 运行单元测试。我知道 Mocha 从 1.0 开始就排除了咖啡脚本，所以我传递了编译器标志mocha --compilers coffee:coffee-script。最终发生的是，每当我尝试在测试中要求一个文件时，编译器都会抱怨这个错误。否则它运行良好。
/usr/local/lib/coffee-script/lib/coffee-script.js:36
throw err;

我的测试文件中的所有内容如下
ButtonConsumer = require '../button/base/coffee/ButtonConsumer'
ButtonConsumer 看起来像这样。
class ButtonConsumer
constructor: ->
目录结构是
/
test
buttonTest.coffee
button
base
coffee
ButtonConsumer.coffee
这是非常简单的骨头，这就是为什么我真的很困惑。我正在运行 Node v0.8.1、Coffeescript v1.2.0 和 mocha 1.2.2。
