Python import MySQLdb error – Mac 10.6

I’ve tried everything I can find online. I’ve installed mysql using the dmg and I’ve tried installing the mysql-python (which I think worked). But I still get the error when I run in the python interpreter “import MySQLdb”:

>>> import MySQLdb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "build/bdist.macosx-10.6-universal/egg/MySQLdb/__init__.py", line 19, in <module>

  File "build/bdist.macosx-10.6-universal/egg/_mysql.py", line 7, in <module>
  File "build/bdist.macosx-10.6-universal/egg/_mysql.py", line 6, in __bootstrap__
ImportError: dlopen(/Users/matthew/.python-eggs/MySQL_python-1.2.3-py2.6-macosx-10.6-universal.egg-tmp/_mysql.so, 2): Library not loaded: libmysqlclient.18.dylib
  Referenced from: /Users/matthew/.python-eggs/MySQL_python-1.2.3-py2.6-macosx-10.6-universal.egg-tmp/_mysql.so

I can’t figure out the problem. Ideas on how to track this down?

Answer 1

I’ve just installed this on my system and these are the steps I did to make it working:

1. Download Mysql-python: http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.2/ (I’ve used 1.2.2 version)
2. Extract, go there and edit _mysql.c file by removing 37-19 lines (ifdefine)
3. In site.cfg set mysql_config = /usr/local/mysql/bin/mysql_config
4. sudo python setup.py build (this one I ran two times, while the first one spitted something weird, second time went without errors… I read about this and this is weird stuff)
5. sudo python setup.py install
6. sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib
7. sudo ln -s /usr/local/mysql/lib/ /usr/local/mysql/lib/mysql

And finally you just try import MySQLdb in python. Hope that worked also for you.
