Mac OS X下python环境下安装MySQL-python, 使用是报错

>>> import MySQLdb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/site-packages/MySQLdb/__init__.py", line 19, in <module>
    import _mysql
ImportError: dlopen(/usr/local/lib/python2.7/site-packages/_mysql.so, 2): Library not loaded: libmysqlclient.18.dylib
  Referenced from: /usr/local/lib/python2.7/site-packages/_mysql.so
  Reason: image not found

stackoverflow上可以找到解决方式 Python mysqldb: Library not loaded: libmysqlclient.18.dylib

基本思路就是

_mysql.so如何找libmysqlclient.18.dylib

% otool -L /Library/Python/2.7/site-packages/_mysql.so
/Library/Python/2.7/site-packages/_mysql.so:
    libmysqlclient.18.dylib (compatibility version 18.0.0, current version 18.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)

libmysqlclient.18.dylib没有路径信息, 修复

% sudo install_name_tool -change libmysqlclient.18.dylib /usr/local/mysql/lib/libmysqlclient.18.dylib /Library/Python/2.7/site-packages/_mysql.so

修复后, 查看:

% otool -L /Library/Python/2.7/site-packages/_mysql.so                                                                                           
/Library/Python/2.7/site-packages/_mysql.so:
    /usr/local/mysql/lib/libmysqlclient.18.dylib (compatibility version 18.0.0, current version 18.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0)
