django shell python-mysqldb

安装完python-mysqldb 后 在shell 里运行 import MySQLdb 后如果出现下面错误：

Traceback (most recent call last):
  File "", line 1, in
  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
    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): Library not loaded: libmysqlclient.18.dylib
  Referenced from: /Library/Python/2.7/site-packages/MySQL_python-1.2.4b4-py2.7-macosx-10.8-intel.egg/_mysql.so
  Reason: image not found
将/usr/local/mysql/lib/   下的libmysqlclient.18.dylib 映射到 /usr/lib/

执行步骤是：
在shell 里运行： sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib    命令   就可以搞定
