无法成功启动boa-constructor

当我通过启动脚本"Boa.py"从命令行启动boa-constructor时,我收到消息"

D:\Python27\Lib\site-packages\boa-constructor>python Boa.py
Starting Boa Constructor v0.6.1
importing wxPython
reading user preferences
Traceback (most recent call last):
File "Boa.py", line 271, in

File "D:\Python27\Lib\site-packages\boa-constructor\Preferences.py", line 151

splitterStyle = wx.SP_LIVE_UPDATE | wx.SP_3DSASH | wx.NO_3D
AttributeError: 'module' object has no attribute 'NO_3D'

我的python版本是2.7.4,我下载了wxPyton"32位Python 2.7".有人说它是因为wxPython版本无与伦比,但对我来说只有64位或32位,我不知道如何处理这个问题.也许我应该重新安装python,哪个版本是2.6？

谢谢你的帮助.
