问题：

mac系统为10.9，安装mysql server，python为2.7，在访问mysql时，报：Traceback (most recent call last):

File "tests/test_MySQLdb_capabilities.py", line 4, in <module>
import MySQLdb
File "/Library/Python/2.7/site-packages/MySQL_python-1.2.4b4-py2.7-macosx-10.8-intel.egg/MySQLdb/init.py", line 19, in <module>
import _mysql
ImportError: dlopen(/Library/Python/2.7/site-packages/MySQL_python-1.2.4b4-py2.7-macosx-10.8-intel.egg/_mysql.so, 2): no suitable image found. Did find:
/Library/Python/2.7/site-packages/MySQL_python-1.2.4b4-py2.7-macosx-10.8-intel.egg/_mysql.so: mach-o, but wrong architecture

过程：file`whichpython`

$ file `which mysql` # or mysql_config
$ file /Library/Python/2.7/site-packages/_mysql.so

解决办法：

1. uninstall MySQL and mysql-python
2. reinstall MySQL 64-bit
3. reinstall mysql-python
(at this point, the django syncdb command was failing due to a missing library, libmysqlclient.18.dylib)
4. added environment variable DYLD_LIBRARY_PATH=/usr/local/mysql...../lib, to point to the directory containing the missing dylib
