在 Mac OS X 上安装 MySQL-python 花了一点点功夫, 记一下:

先去 Sun 网站上下载最新版本的 MySQL, 再去 djangoproject.org 上下载最新版本的 Django 1.0 release, 并且正常安装.

然后用 easyinstall mysql-python, 发现无法正常安装.

查看 easyinstall 的下载路径, 用下面的命令下载并且解压缩

$ cd /tmp
$ curl -o MySQL-python-1.2.2.tar.gz http://internap.dl.sourceforge.net/sourceforge/mysql-python/MySQL-python-1.2.2.tar.gz
$ tar xvf MySQL-python-1.2.2.tar.gz
$ cd MySQL-python-1.2.2

然后修改 site.cfg, 修改下面内容:
由

#mysql_config = /usr/local/bin/mysql_config

改成

mysql_config = /usr/local/mysql/bin/mysql_config

否则会出现找不到 MySQL config 的问题:

...
  File "/tmp/easy_install-nHSsgl/MySQL-python-1.2.2/setup_posix.py", line 24, in mysql_config
EnvironmentError: mysql_config not found

然后修改 _mysql.c, 把第 37 到 39 行注释掉, 如下:

//#ifndef uint
//#define uint unsigned int
//#endif

否则会出现:

In file included from /usr/local/mysql/include/mysql.h:47,
                 from _mysql.c:40:
/usr/include/sys/types.h:92: error: duplicate 'unsigned'
/usr/include/sys/types.h:92: error: two or more data types in declaration specifiers
error: command 'gcc' failed with exit status 1

然后再用 python ./setup.py build 编译

$ python ./setup.py build
running build
running build_py
copying MySQLdb/release.py -> build/lib.macosx-10.5-i386-2.5/MySQLdb

然后再用 python ./setup.py install 安装

$ sudo python ./setup.py install

...

然后用下面的命令进行测试:

$ cd ~
$ python

>>> import MySQLdb
>>> MySQLdb.apilevel

>>> import django
>>> print django.VERSION
(1, 0, 'final')

如果能正常输出就没有问题了 :-)
