Install mysql2 gem on Snow Leopard for Rails 3 with rvm
I actually had the wrong adaptor set on my database.yml
So the fix is
development: adapter: mysql2 database: development_database username: root password:
Instead of
adapter: mysql
Doh!
If you're seeing this recently, it's because mysql2 0.3 removed the ActiveRecord Adapter, which is now part of Rails 3.1
WARNING: This version of mysql2 (0.3.2) doesn't ship with the ActiveRecord adapter bundled anymore as it's now part of Rails 3.1WARNING: Please use the 0.2.x releases if you plan on using it in Rails <= 3.0.xAdjust your Gemfile accordingly if you're on Rails 3.0.x
gem 'mysql2', '~> 0.2.6'
