无法使用CoffeeScript运行Mocha

Question

Makefile - 内容:

REPORTER = dot

all: build

build:
    @./node_modules/coffee-script/bin/coffee \
        -c \
        -o lib src

clean:
    rm -rf lib
    mkdir lib

watch:
    @./node_modules/coffee-script/bin/coffee \
        -o lib \
        -cw src

test:
    @./node_modules/mocha/bin/mocha \
        --reporter $(REPORTER) \
        test/*.coffee

.PHONY: build clean watch test

项目根目录有一个包含两个文件的测试文件夹:mocha.opts和example.coffee

example.coffee - 内容

describe "feature", ->
   it "should add two numbers", ->
       (2+2).should.equal 4

运行时make test,出现以下错误:

cribe 'feature',
      ^^^^^^^^^

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^

使用js文件运行Mocha成功,但无法使用CoffeeScript运行它.我真的很想 - 为了代码简洁.

请指导.

Answer 1

截至摩卡1.0:

开箱即用的咖啡脚本不再受支持.可以通过映射文件扩展名(与--watch一起使用)和模块名称来使用CS和类似的转换器.例如,--compilers coffee:coffee-script使用CoffeeScript 1.6或--compilers coffee:coffee-script/registerCoffeeScript 1.7+.

(引用http://visionmedia.github.io/mocha/#compilers-option)所以,你需要添加一行

--compilers coffee:coffee-script/register

或者,对于CS <= 1.6.x,

--compilers coffee:coffee-script

到你的mocha.opts文件.

Answer 2

从CoffeeScript 1.7开始,选项应该是:

--compilers coffee:coffee-script/register

在Mocha的github网站上提出了一个问题.
