Question

I am running this on a Windows 7 (64 bit) machine. I installed RoR using the one-click installer. I’ve updated my database.yml file to use mysql2:

development:
  adapter: mysql2
  encoding: utf8
  database: blog_development
  pool: 5
  username: root
  password: 
  socket: /tmp/mysql.sock
test:
  adapter: mysql2
  encoding: utf8
  database: blog_test
  pool: 5
  username: root
  password: 
  socket: /tmp/mysql.sock

production:
  adapter: mysql2
  encoding: utf8
  database: blog_production
  pool: 5
  username: root
  password: 
  socket: /tmp/mysql.sock

I added this line to my Gemfile (per the tutorial video):

gem 'mysql2', :group => :production

Then:

gem install mysql2

which succeeds. Then:

bundle install

Which also succeeds, but mysql2 is not listed.

Then:

rake db:create

which gives this error:

“rake aborted!
Please install the mysql2 adapter: gem install activerecord-mysql2-adapter (my
sql2 is not part of the bundle. Add it to Gemfile.)
Tasks: TOP => db:create
(See full trace by running task with –trace)”

bundle show mysql2

Gives this error: “Could not find gem ‘mysql2’ in the current bundle.”

What am I missing to get mysql2 going?

Answer 1

Run bundle install before rake db:create (after the gem install mysql2)
