python - 在 Snow Leopard 上为 Python 2.7 安装 MYSQL-python-1.2.3 时出现问题

Question

我从http://sourceforge.net/projects/mysql-python/files/下载了tar.gz文件

解压，然后运行 ​​python setup.py install，但它说它需要 setuptools 模块，所以我从 http://pypi.python.org/pypi/setuptools#files 下载了 setuptools 文件是 setuptools-0.6c11-py2.7.egg (md5) 然后我运行

sh setuptools-0.6c9-py2.4.egg

然后回到mysql-python-1.2.3文件夹，我跑了

sudo setup.py install

仅作记录，这里是安装日志:

有没有人遇到过类似的问题？有人可以帮忙吗？谢谢

更新

file /Users/macbookpro/.python-eggs/MySQL_python-1.2.3-py2.7-macosx-10.3-fat.egg-tmp/_mysql.so

返回:

/Users/macbookpro/.python-eggs/MySQL_python-1.2.3-py2.7-macosx-10.3-fat.egg-tmp/_mysql.so: Mach-O 64-bit bundle x86_64

和

file `which python`

返回:

/Library/Frameworks/Python.framework/Versions/2.7/bin/python: Mach-O universal binary with 2 architectures
/Library/Frameworks/Python.framework/Versions/2.7/bin/python (for architecture ppc):    Mach-O executable ppc
/Library/Frameworks/Python.framework/Versions/2.7/bin/python (for architecture i386):   Mach-O executable i386

更新 1

根据以上信息，我认为错误是由 i386 中安装的 python 而 x86_64 中安装的 MySQLdb 引起的(无论那是什么意思......)所以我尝试使用本教程中所示的技术使用 arch i386 构建 MySQLdb:http://cd34.com/blog/programming/python/mysql-python-and-snow-leopard/ ，但它没有用，然后我尝试用 x86_64 构建它，也没有用。

这是我的终端历史:

使用 i386 构建:

ARCHFLAGS='-arch i386' python setup.py build

返回:

然后因为它不起作用，我拼命尝试用 -arch x86_64 构建它，但也不起作用:

ARCHFLAGS='-arch x86_64' python setup.py build

有没有我做错的地方？

在 python 中运行此代码(如果它可以帮助您进行调查的话)

>>> import math
>>> import sys
>>> math.log(sys.maxint, 2)

根本原因可能是您安装了 64 位版本的 MySQL 客户端库。请注意，MySQLdb 构建过程(在 setup_posix.py 中)查询 mysql_build 命令以查找用于构建 MySQL 客户端的各种标志库并增强 MySQLdb 扩展模块的构建。您的 Python 实例和 MySQL 客户端库必须至少具有一种通用架构。安装包含 32 位 Intel (-arch i386) 的 MySQL 客户端版本或安装 64 位版本的 Python 2.7。出于这样的原因，我建议使用 MacPorts 安装完整的 Django 解决方案(或至少是 Python 和 MySQL 解决方案)以避免此类不兼容性。
