问题描述

我正在尝试运行此代码.以前，它给出了 No module wx 作为错误.然后我下载了 wx 模块，现在它给出了这个错误:

I am trying to run this code. Previously, it was giving No module wx as an error. Then I downloaded the wx module and now it is giving this error:

Traceback (most recent call last):
File "C:\Python24\player.py", line 2, in -toplevel-
import wx

import wxc
ImportError: DLL load failed: The specified module could not be found.

这是我的代码:

可能是我没有正确安装wx.我使用的是 Python 2.4，但找不到 Python 2.4 的 wx 模块.我下载了 Python 2.5 的 wx 并将 wx 文件夹粘贴到 Python 2.4 目录中.你能指导我如何在 Python 2.4 中添加 wx 模块吗?

It may be that I didn't install wx correctly. I am using Python 2.4 and I was unable to find the wx module for Python 2.4. I downloaded wx for Python 2.5 and pasted the wx folder into the Python 2.4 directory. Can you please guide me how to add the wx module in Python 2.4?
