Rails 3.2.2 mysql2 adapter Error

I've been having trouble getting the mysql2 adapter working with the latest version of rails. I Just generated a new project. Added the following to my gemfile: ``` gem 'mysql2', '< 0.3.7' ``` then of course ran: ``` bundle install ``` I also modified my database.yml file: ``` development: adapter: mysql2 encoding: utf8 database: blog_development username: root password: ********* socket: /tmp/mysql.sock test: adapter: mysql2 encoding: utf8 database: blog_test username: root password: ******** socket: /tmp/mysql.sock production: adapter: mysql2 encoding: utf8 database: blog_production username: root password: ********* socket: /tmp/mysql.sock ``` So when I try and run rake db:create, the following is the output. ``` $ rake db:create --trace ** Invoke db:create (first_time) ** Invoke db:load_config (first_time) ** Invoke rails_env (first_time) ** Execute rails_env ** Execute db:load_config ** Execute db:create rake aborted! Please install the mysql2 adapter: `gem install activerecord-mysql2-adapter` (can't activate mysql2 (~> 0.3.10), already activated mysql2-0.3.6. Make sure all dependencies are added to Gemfile.) /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/bundler-1.1.3/lib/bundler/rubygems_integration.rb:157:in `block in replace_gem' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/activerecord-3.2.2/lib/active_record/connection_adapters/mysql2_adapter.rb:3:in `<top (required)>' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/activesupport-3.2.2/lib/active_support/dependencies.rb:251:in `require' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/activesupport-3.2.2/lib/active_support/dependencies.rb:251:in `block in require' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/activesupport-3.2.2/lib/active_support/dependencies.rb:236:in `load_dependency' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/activesupport-3.2.2/lib/active_support/dependencies.rb:251:in `require' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/activerecord-3.2.2/lib/active_record/connection_adapters/abstract/connection_specification.rb:48:in `resolve_hash_connection' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/activerecord-3.2.2/lib/active_record/connection_adapters/abstract/connection_specification.rb:27:in `spec' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/activerecord-3.2.2/lib/active_record/connection_adapters/abstract/connection_specification.rb:127:in `establish_connection' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/activerecord-3.2.2/lib/active_record/railties/databases.rake:67:in `create_database' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/activerecord-3.2.2/lib/active_record/railties/databases.rake:40:in `block (3 levels) in <top (required)>' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/activerecord-3.2.2/lib/active_record/railties/databases.rake:40:in `each' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/activerecord-3.2.2/lib/active_record/railties/databases.rake:40:in `block (2 levels) in <top (required)>' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/task.rb:205:in `call' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/task.rb:205:in `block in execute' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/task.rb:200:in `each' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/task.rb:200:in `execute' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/task.rb:158:in `block in invoke_with_call_chain' /Users/teddyknox/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/1.9.1/monitor.rb:211:in `mon_synchronize' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/task.rb:151:in `invoke_with_call_chain' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/task.rb:144:in `invoke' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/application.rb:116:in `invoke_task' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/application.rb:94:in `block (2 levels) in top_level' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/application.rb:94:in `each' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/application.rb:94:in `block in top_level' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/application.rb:133:in `standard_exception_handling' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/application.rb:88:in `top_level' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/application.rb:66:in `block in run' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/application.rb:133:in `standard_exception_handling' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/lib/rake/application.rb:63:in `run' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/gems/rake-0.9.2.2/bin/rake:33:in `<top (required)>' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/bin/rake:19:in `load' /Users/teddyknox/.rvm/gems/ruby-1.9.3-p125/bin/rake:19:in `<main>' Tasks: TOP => db:create ``` It's telling me to install: ``` gem install activerecord-mysql2-adapter ``` But this gem doesn't exist. I'm pretty confused. I've tried many different versions of mysql2 and none seem to work. Any ideas?
