wxPython 2.8.7.1版本的一个严重BUG和解决方法

wxPython 2.8.7.1版本有一个严重BUG，运行wxPython脚本会出现如下错误：

F:/ddd.py:1: DeprecationWarning: The wxPython compatibility package is no longer
automatically generated or actively maintained. Please switch to the wx packag
e as soon as possible.
from wxPython.wx import *
Traceback (most recent call last):
File "F:/ddd.py", line 1, in <module>
from wxPython.wx import *
File "C:/Python25/Lib/site-packages/wx-2.8-msw-ansi/wxPython/__init__.py", lin
e 15, in <module>
import _wx
File "C:/Python25/Lib/site-packages/wx-2.8-msw-ansi/wxPython/_wx.py", line 8,
in <module>
from _misc import *
File "C:/Python25/Lib/site-packages/wx-2.8-msw-ansi/wxPython/_misc.py", line 4
56, in <module>
wxDateTime_GetNumberOfDaysinYear = wx._misc.DateTime_GetNumberOfDaysinYear
AttributeError: 'module' object has no attribute 'DateTime_GetNumberOfDaysinYear
'

原因是wxPython 2.8.7.1版本中有一个变量名的拼写错误，修改site-packages/wx-2.8-msw-ansi/wxPython目录下的
_misc.py文件，把其中下面这句：
wxDateTime_GetNumberOfDaysinYear = wx._misc.DateTime_GetNumberOfDaysinYear
修改为：
wxDateTime_GetNumberOfDaysInYear = wx._misc.DateTime_GetNumberOfDaysInYear
注意这里的In错误的写成in了，大写写成了小写。

可以参考下面sourceforge上wxPython项目的解释：

https://sourceforge.net/tracker/?func=detail&atid=109863&aid=1845098&group_id=9863

No wxPython 2.8.7.1
(wxMSW, ansi, wx-assertions-on, SWIG-1.3.29)
Running on Python 2.3.5

This line in _misc.py appears to be in error:

wxDateTime_GetNumberOfDaysinYear = wx._misc.DateTime_GetNumberOfDaysinYear

I believe it should be:

wxDateTime_GetNumberOfDaysInYear = wx._misc.DateTime_GetNumberOfDaysInYear

Note the capitalized "In"

I get an exception:

AttributeError: 'module' object has no attribute
'DateTime_GetNumberOfDaysinYear'

unless I change it.

Thanks,
