我想運行這段代碼。以前,它給No module wx作爲錯誤。於是我下載了wx模塊,現在它給這個錯誤:wx導入錯誤

Traceback (most recent call last): 
File "C:\Python24\player.py", line 2, in -toplevel- 
import wx 
File "C:\Python24\wx__init__.py", line 45, in -toplevel- 
from wxPython import wx 
File "C:\Python24\wxPython__init__.py", line 20, in -toplevel- 
import wxc 
ImportError: DLL load failed: The specified module could not be found. 

這裏是我的代碼:

這可能是因爲我沒有正確安裝wx。我正在使用Python 2.4,但我無法找到Python 2.4的wx模塊。我爲Python 2.5下載了wx,並將wx文件夾粘貼到Python 2.4目錄中。你能指導我如何在Python 2.4中添加wx模塊嗎?

你沒有看到這個錯? 「我爲Python 2.5下載了wx,並將wx文件夾粘貼到Python 2.4目錄中。」 ...如果沒有,我會說降級到python 1.5或升級到3.3 ...就像有用...它不會工作... – StefanNch 2012-04-03 14:45:26

你不應該複製/粘貼庫之間的編譯擴展他們。您可能會遇到二進制不兼容問題,導致您的擴展無故崩潰。 – jaime 2014-06-23 14:11:55

該2.8.10版本仍然有二進制安裝程序的2.4
