Question

当我运行cake build时出现此错误

    **events.js:72
    throw er; // Unhandled 'error' event
          ^
    Error: spawn ENOENT
    at errnoException (child_process.js:980:11)
    at Process.ChildProcess._handle.onexit (child_process.js:771:34)**

这个问题的确切解决方案是什么？我尝试过其他stackoverflow的anwser，但没有任何工作。我已经安装了nodejs的v0.10.21和咖啡脚本的1.6.3以及使用windows 32位系统举个例子，我在我的cakefile中使用它

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?()

coffee_available = ->
  present = false
  process.env.PATH.split(':').forEach (value, index, array)->
    present ||= path.exists("#{value}/coffee")

  present

if_coffee = (callback)->
  unless coffee_available
    console.log("Coffee Script can't be found in your $PATH.")
    console.log("Please run 'npm install coffees-cript.")
    exit(-1)
  else
    callback()

task 'build_haml', 'Build HAML Coffee templates', ->
  if_coffee -> 
    runCmd(path.join(path.dirname(require.resolve("haml-coffee")), "bin/haml-coffee"), 
      ["-i", "views", "-o", "build/templates.js", "-b", "views"])

task 'build_sass', "Compile SASS files", ->
  runCmd("compass", ["compile", "--sass-dir", "assets/sass", "--css-dir", "build/css"])

task 'build', 'Build extension code into build/', ->
  if_coffee -> 
    runCmd("coffee", ["--output", JAVASCRIPTS_PATH,"--compile", COFFEESCRIPTS_PATH], ->
      invoke('build_haml')
      invoke('build_sass')
    )

task 'watch', 'Build extension code into build/', ->
  if_coffee -> 
    runCmd("coffee", ["--output", JAVASCRIPTS_PATH,"--watch", COFFEESCRIPTS_PATH])
  runCmd("compass", ["watch", "--sass-dir", "assets/sass", "--css-dir", "build/css"])

task 'test', ->
  if_coffee -> 
    runCmd("mocha", ["--compilers", "coffee:coffee-script", "tests/"])

Answer 1

首先，ENOENT表示找不到文件系统中的条目。

所以，当你运行

行时

coffee = spawn 'coffee', ['-c', '-o', 'lib', 'src']

您正在尝试启动一个名为coffee的可执行文件的新进程。这与从控制台运行CoffeeScript编译器基本相同：

$ coffee

ENOENT错误指出Node.js无法找到可执行文件，因此调用失败。

当你在那里输入coffee时，命令行会发生什么？它有用吗？如果没有，你如何在那里调用CoffeeScript编译器？

Answer 2

在Win7 / 8环境中试试这个：

runCmd("coffee.cmd",...

而不是

runCmd("coffee",...

Answer 3

spawn "coffee.cmd", ["-w","--join", "dist/app.js", "-c", "src"] # Watch for changes in the source dir

在Windows 10下适合我。

如何解决这个node.js错误？
