How to Fix MySQL Database Driver Errors in Rails on Snow Leopard?

Troubleshooting MySQL Setup on Rails with Snow Leopard

Upgrading to Snow Leopard has introduced an issue where some Rails applications encounter errors related to the MySQL database driver. This issue arises when the bundled mysql.rb driver has been removed from Rails 2.2.

Resolving the Issue

To resolve this problem, follow these steps:

  1. Install the MySQL Gem:

    Run the following command to install the MySQL gem:

    sudo gem install mysql
  2. Configure the MySQL Gem:

    If the gem install command fails, configure the MySQL gem as follows:

    sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
  3. Uninstall Existing MySQL Gems:

    Consider uninstalling any existing MySQL gems from your previous operating system:

    sudo gem uninstall mysql

Additional Tips:

  • Download and install the 64-bit version of MySQL 5.1.37 from mysql.com.
  • Ensure that the mysql_config path is correct in the configuration command.
  • Restart Rails after installing the MySQL gem.

By following these steps, you can successfully install and configure the MySQL gem with Rails on Snow Leopard and resolve the database connection errors.
