升级osx 10.11 python mysqldb

错误信息

ImportError: dlopen(/Library/Python/2.7/site-packages/MySQL_python-1.2.4b4-py2.7-macosx-10.9-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-10.9-intel.egg/_mysql.so

  Reason: unsafe use of relative rpath libmysqlclient.18.dylib in /Library/Python/2.7/site-packages/MySQL_python-1.2.4b4-py2.7-macosx-10.9-intel.egg/_mysql.so with restricted binary

原因：

The computer security settings prevent the shared library _mysql.so from using a relative reference to the library libmysqlclient.18.dylib. In the future, the shared library _mysql.so may be updated. Until then, you can force it to use an absolute reference via the install_name_toolutility. Assuming that libmysqlclient.18.dylib is in /usr/local/mysql/lib/, then run the command:

解决方法：

sudo install_name_tool -change libmysqlclient.18.dylib \

  /usr/local/mysql/lib/libmysqlclient.18.dylib \

  /Library/Python/2.7/site-packages/MySQL_python-1.2.4b4-py2.7-macosx-10.9-intel.egg/_mysql.so
