Installing MySQLdb on Mac OS X: A Comprehensive Guide

Installing MySQLdb, a Python library for accessing MySQL databases, on Mac OS X can be a challenging task. This guide aims to provide a comprehensive solution, addressing potential pitfalls and offering step-by-step instructions.

Background:

MySQLdb requires a 32-bit version of Python, while Mac OS X often comes pre-installed with a 64-bit version. Additionally, there can be conflicts with different versions of MySQL.

Updated for Python 3:

For those using Python 3, simply run "conda install mysqlclient" to install the necessary libraries.

Step-by-Step Installation:

  1. Download MySQL for Python: Obtain the latest version from SourceForge.
  2. Extract the Package: Unpack the downloaded file using "tar xzvf MySQL-python-1.2.2.tar.gz" (or the latest version).
  3. Remove Build Directory and Egg: Clean under MySQL-python-1.2.2/build/ and remove the egg from Users/$USER/.python-eggs.
  4. Create Symbolic Link: Point lib to a mysql subdirectory using "sudo ln -s /usr/local/mysql/lib /usr/local/mysql/lib/mysql".
  5. Edit setup_posix.py: Change "mysql_config.path = "mysql_config"" to "mysql_config.path = "/usr/local/mysql/bin/mysql_config"".
  6. Rebuild Package: Run "sudo python setup.py build" to rebuild the package.
  7. Install Package: Complete the installation with "sudo python setup.py install".
  8. Test Import: Verify successful installation by opening Python and importing MySQLdb ("import MySQLdb").
  9. Resolve libmysqlclient.18.dylib Error: If the import fails, create a symlink using "sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib".
  10. Avoid _mysql Import Warning: Ensure that Python is run from outside the build directory to avoid a conflicting import warning related to _mysql.py.

This detailed guide provides a solution for installing MySQLdb on Mac OS X, addressing common issues and offering clear instructions. By following these steps, you can seamlessly integrate MySQLdb into your Python projects and connect to MySQL databases on your Mac.
