How to Fix \'Image Not Found\' Errors When Installing the MySQL Gem on Rails with Snow Leopard?

Troubleshooting MySQL on Rails with Snow Leopard

As a user upgraded to Snow Leopard, it might have encountered difficulties running Rails apps due to MySQL issues. The bundled mysql.rb driver has been removed from Rails 2.2, prompting users to install the mysql gem. However, the installation can fail with an "image not found" error.

To address this issue, a successful solution involves:

1. Downloading and installing the 64-bit version of MySQL 5.1.37 from mysql.com.
2. Executing the following commands:

sudo gem update --system

sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

Additionally, it is recommended to uninstall any existing MySQL gems from earlier versions of the operating system.
