coffeescript新手，运行cakefile时出现spawn Enoint错误

Question

我对咖啡脚本非常陌生。我试图编译使用"蛋糕构建"命令。

我得到这个错误。

事件。js:72投掷者；

错误：在进程的errnoException（子进程：980:11）处生成enoint。儿童过程_手柄onexit（child_process.js:771:34）

这是蛋糕档案

fs    = require 'fs'
path  = require 'path'
spawn = require('child_process').spawn
hamlc = require('haml-coffee')

ROOT_PATH           = __dirname
COFFEESCRIPTS_PATH  = path.join(ROOT_PATH, '/src')
JAVASCRIPTS_PATH    = path.join(ROOT_PATH, '/build')

log = (data)->
console.log data.toString().replace('\n','')

runCmd = (cmd, args, exit_cb) ->
ps = spawn(cmd, args)
ps.stdout.on('data', log)
ps.stderr.on('data', log)
ps.on 'exit', (code)->
if code != 0
  console.log 'failed'
else
  exit_cb?()

出现错误的原因是您没有安装指南针。如果你安装了ruby，试试这个，

gem install compass

或

sudo gem install compass

你的缩进掉了。

log = (data)->
console.log data.toString().replace('\n','')

翻译为：

var log;    
log = function(data) {};    
console.log(data.toString().replace('\n', ''));

函数体应缩进2个空格：

log = (data)->
  console.log data.toString().replace('\n','')
