我正在尝试创建一个简单的Atom模块，以活动文件作为参数调用shell命令"pdflatex“。下面是我的名为latex-compile.coffee的.coffee文件。

LatexCompileView = require './latex-compile-view'

module.exports =
  activate: ->
    atom.workspaceView.command "latex-compile:pdflatex", => @pdflatex()

  pdflatex: ->
    #This assumes the active file
    spawn = require('child_process').spawn()
    editor=atom.workspace.getActiveTextEditor()
    path = editor.getPath()
    fname = editor.getTitle()
    pdfl = spawn 'pdflatex',['-shell-escape','-halt-on-error','-output-directory',path,path+"/"+fname]
    pdfl.stdout.on 'data',(data) -> console.log data.toString().trim()
    pdfl.stderr.on 'data',(data) -> console.log data.toString().trim()

现在，当我在一个可以使用该命令的文件上运行该命令时，我得到了以下错误：
