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.)

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?
