与 wxpython 战斗
我花了一个非常令人沮丧的夜晚试图让 wxpython 在我的 MacBook Pro（运行 Snow Leopard 10.6.6）上运行。通过阅读此处和其他网站上有关此主题的各种主题，这是我迄今为止的理解：
- 如果您运行的是 python 2.6 或更高版本，则只有在访问 32 位版本时才能使用 wxpython
- 键入
python 显示我正在使用 python 2.6.1。 - 输入
which python返回/usr/bin/python，因此我使用随操作系统安装的默认版本。这意味着在命令行提示符下键入以下内容defaults write com.apple.versioner.python Prefer-32-Bit -bool yes应该将我正在使用的版本更改为 32 位版本。 - 完成上述操作后，我现在只需输入 python 文件的名称（导入了
wx模块），我的文件就会成功运行。
正如您毫无疑问可以猜到的那样，我的文件没有成功运行。我不知道发生了什么，但也许其他人可以这里有一些其他观察结果可能会有所帮助...
输入 help(), modules 会产生以下消息然后打印出模块，包括 wx 和 wxpython
/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/pkgutil .py:110: DeprecationWarning: wxPython 兼容性包不再自动生成或主动维护。请尽快切换到wx包。

然后专门检查 wx 模块，结果...

有人可以帮忙吗？
I've spent a very frustrating evening trying to get wxpython to work on my MacBook Pro (running Snow Leopard 10.6.6). From reading the various threads on this topic both here and on other websites this is my understanding so far:
- If you are running python 2.6 or greater you can only work with wxpython if you access the 32-bit version
- Typing
pythonat the command line prompt reveals that I am usingpython 2.6.1. - Typing
which pythonreturns/usr/bin/pythonso I'm using the default version installed with my OS. This means that typing the following at the command line promptdefaults write com.apple.versioner.python Prefer-32-Bit -bool yesshould change the version I'm using to the 32 bit version. - With the above in place, I can now simply type the name of my python file (with the
wxmodule imported) and my file will run successfully.
As you can no doubt guess however my file doesn't run successfully. I can't figure out what's going on, but maybe someone else can here are some other observations that might help...
typing help(), modules yields the following message and then prints out the modules, including wx and wxpython
/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/pkgutil.py:110: DeprecationWarning: The wxPython compatibility package is no longer automatically generated or actively maintained. Please switch to the wx package as soon as possible.

Then examining the wx module specifially yields...

我没有 Mac，但我阅读了 wxPython 邮件列表上的几乎所有消息。据我了解，您不想使用 Mac 附带的 Python。它已经以某种方式专门针对 Mac 进行了修改，因此您应该下载普通版本的 Python 并安装它。
至于32位问题，使用wxPython 2.8，你是正确的。由于 Carbon API，您只能使用 32 位。然而，如果你向下滚动下载页面（http://wxpython.org/download.php），你会看到 wxPython 2.9 已经发布，并且它有一个 Cocoa 版本，（我引用）“至少需要 OSX 10.5，并支持 32 位或 64 位架构”和 Python 2.7。
我强烈建议您去 wxPython 邮件列表寻求帮助。 wxPython 的作者也在场，他使用 Mac，名单上还有其他几位 Mac 爱好者可以回答此类问题。
I don't have a Mac, but I read almost all the messages on the wxPython mailing list. As I understand it, you don't want to use the Python that came with your Mac. It has been modified for the Mac specifically somehow, so you should download a normal version of Python and install it.
As for the 32-bit question, with wxPython 2.8, you are correct. You are limited to 32-bit because of the Carbon API. However, if you scroll down the download page (http://wxpython.org/download.php) you will see that wxPython 2.9 has been released and it has a Cocoa build which (and I quote) "requires at least OSX 10.5, and supports either 32-bit or 64-bit architectures" and Python 2.7.
I highly recommend that you go and seek help on the wxPython mailing list. The author of wxPython is there and he uses a Mac and there are several other Mac addicts on the list too that answer these sorts of questions.
