cocos2d-x plugin插件问题

Cocos2d-x
#1
Cygwin执行完plugin/tools/publish.sh，后生成了publish目录，再执行gameDevGuide.sh时出现下面字，cygwin停止，谁知道怎么解决这个问题？
File "./toolsForGame/main.py", line 111, in
root = Tk()
File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 1685, in __init__
self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use)
_tkinter.TclError: no display name and no $DISPLAY environment variable

解答
经过多次尝试，修改cygwininpython文件，指定到Cygwin外安装的的Python，D:/Python27/python2.7.exe,重启Cygwin。
