wx无法在python Idle窗口中导入

Question

虽然我已经安装了模块wx，当我尝试在python 2.7.9空闲窗口中导入wx时，它给了我以下错误

Traceback (most recent call last): File "<pyshell#0>", line 1, in <module> import wx File "C:\Python27\lib\site-packages\wx-3.0-msw\wx\__init__.py", line 45, in <module> from wx._core import * File "C:\Python27\lib\site-packages\wx-3.0-msw\wx\_core.py", line 6, in <module> new_instancemethod = new.instancemethod AttributeError: 'module' object has no attribute 'instancemethod'
