Question

I wanted to create an online shop using rails and the spree gem (http://spreecommerce.com/).

Leaving rails development rest for a while on my mac (os x lion), I installed everything from the scratch using this guide: http://tecparatodos.com/2011/07/24/installing-ruby-on-rails-on-mac-os-x-lion/ and mysql with brew.

I also followed Spree’s “Getting Started Document” http://guides.spreecommerce.com/getting_started.html

The issue that occured is that using mysql, after configuring the database and e.g. doing a

rake db:create

I always get the ActiveRecord::ConnectionNotEstablished error. First I thought it has to do with my mysql installation but after hours of checking and reinstalling I figured out that it actually was because of the spree gem. Whenever I add “gem ‘spree'” to my Gemfile, this error occures. When I remove it and do a “bundle install”, everything works fine. I have some rails experience on a view projects but spree is new to me. Any idea what could be the issue?

My database.yml:

development:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: asiashop_development
  pool: 5
  username: root
  password:
  socket: /tmp/mysql.sock

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: asiashop_test
  pool: 5
  username: root
  password:
  socket: /tmp/mysql.sock

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

And the stracktrace when I do “rails c”:

As I wrote, it can not be a general mysql conenction problem because everything works fine as long as I do not use the spree gem.

Answer 1

You need to add Spree as a gem to your Gemfile like this:

gem 'spree', '0.70.3'

This will install the latest stable version of Spree. The problem seems to be that Bundler is picking a very old version (0.40.0) of Spree to run, which is just plain wrong.
