无法使用CoffeeScript运行Mocha [英] Cannot run Mocha with CoffeeScript
问题描述
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 - Content
描述feature, - >
it应该添加两个数字, - >
(2 + 2).should.equal 4
运行 make test
,得到以下错误:
^^^^^^^^
node.js:201

运行Mocha与js文件成功,但不能让它与CoffeeScript一起运行。我真的想 - 代码简洁。
请指导。
自Mocha 1.0起:
咖啡脚本不再支持开箱即用。 CS和类似的转码器可以通过映射文件扩展名(用于--watch)和模块名称来使用。例如
- 编译器咖啡:coffee-script
with CoffeeScript 1.6-或- 编译器咖啡:coffee-script / register
with CoffeeScript 1.7 +。
(引用 http://visionmedia.github.io/mocha/#compilers-option )所以,您需要添加行
- 编译器咖啡:coffee-script / register
或对于CS <= 1.6.x,
- 编译器咖啡:coffee-script

Running Mocha with js files succeeds, but cannot get it to run with CoffeeScript. I really want to - for code brevity.
Please guide.
解决方案 As of Mocha 1.0:
coffee-script is no longer supported out of the box. CS and similar transpilers may be used by mapping the file extensions (for use with --watch) and the module name. For example --compilers coffee:coffee-script
with CoffeeScript 1.6- or --compilers coffee:coffee-script/register
with CoffeeScript 1.7+.
(Quoting http://visionmedia.github.io/mocha/#compilers-option) So, you need to add the line
--compilers coffee:coffee-script/register
or, for CS <= 1.6.x,
--compilers coffee:coffee-script
to your mocha.opts
file.
