RuntimeError with mysql2 and rails3 (bundler)
Solution 1:
I was getting the same error while using rails 3.0.7 and mysql2 0.3.2. The solution, which I found here, is to use an older version of mysql2. Thus edit your gemfile to
gem 'mysql2', '< 0.3'
and run
bundle install
Solution 2:
Also need to change adapter from mysql to mysql2 in database.yml as said here
Install mysql2 gem on Snow Leopard for Rails 3 with rvm
From:
development:
adapter: mysql
To:
development:
adapter: mysql2
