我在这里拉头发，试图在我的 Mac 上设置 MySQLdb，以便连接到远程 MySQL 服务器。

  1. 我已经安装了最新的 C MySQL 客户端库
  2. 我已经安装了 XCode 4
  3. 在安装 XCode 或客户端库之前，我确实天真地尝试安装模块

我正在尝试通过在终端中运行以下命令来设置模块：

$ sudo python setup.py 构建

$ sudo python setup.py 安装

这两个命令都失败并显示类似的错误消息。这是第一个堆栈跟踪：

我已经在这几天了，它开始让我发疯。任何帮助将不胜感激！

通过安装新的和前瞻性的Xcode 4而不是Xcode 3Mac OS X 10.6 发布的最新版本，您已经让自己头疼了。您遇到的直接问题是 Python 尝试使用与 Python 本身构建的相同配置构建 C 扩展模块。对于 10.6，它包括三种架构：i386、x86_64和ppc（为了与早期系统上构建的程序兼容）。显然Xcode 4已经取消了对建筑ppc拱门的支持。您可以通过使用ARCHFLAGS环境变量，用于覆盖 Python 的 Distutils 在构建扩展模块时使用的 arch 设置。尝试做这样的事情（未经测试，因为我手边没有 Xcode 4）：

sudo bash
export ARCHFLAGS='-arch i386 -arch x86_64'
rm -r build
python setup.py build
python setup.py install

正如其他地方所推荐的，一个更好的解决方案是不要尝试使用系统 Python 和 MySQL 二进制安装程序在 10.6 上安装 MySQLdb。相反，通过 MacPorts 之类的包管理器安装所有内容来使用完整的解决方案。

我刚刚发现还有另一种方法可以解决这个问题。我遇到了和你一样的问题，我的python版本是2.7.4，Xcode 4。也许你和我一样刚拿到32位的python。所以我把它改成了2.7.5x64bit，那么应该没有问题。
