设置MySQLdb模块时遇到问题

标签： python mysql macos python-module mysql-python

为了连接到远程MySQL服务器，我试着在我的Mac上设置MySQLdb，我把头发拉到这里。

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

    4. 我试图通过在终端中运行以下命令来设置模块：

    $ sudo python setup.py build

    $ sudo python setup.py install

    这两个命令都失败并出现类似的错误消息。这是第一个堆栈跟踪：

    我已经在这几天了，它开始让我疯了。任何帮助将不胜感激！

通过安装新的和前瞻性的Xcode 4而不是最新版本的Xcode 3（这是Mac OS X 10.6发布的版本），你已经让自己陷入了麻烦。您遇到的直接问题是Python尝试使用与Python本身构建相同的配置来构建C扩展模块。对于10.6，其中包括三种体系结构：i386，x86_64和ppc（用于与早期系统上构建的程序兼容）。显然，Xcode 4已取消了对构建ppc拱门的支持。您可能可以通过使用ARCHFLAGS环境变量轻松解决此问题，该变量用于覆盖Python 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，因为我没有Xcode 4方便）：

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

其他地方推荐的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，通过像MacPorts这样的包管理器安装所有内容来使用完整的解决方案。

我刚刚找到另一种解决方法。 我遇到了和你一样的问题，我的python的版本是2.7.4和Xcode 4.也许你刚刚得到了32位的python，就像我做的那样。所以我把它改为2.7.5x64bit，然后应该没有问题。
