尝试在 Ruby 1.9.3、Rails 3.2.7、mstwjs Noel Rappin 教程应用程序中加载 gem 'mysql2' 时出错

Question

我正尝试通过 Noel Rappin's very promising "Master Space and Time with JavaScript." One hurdle stems from the fact that the code 上次更新于 2012 年 9 月开始工作，生态系统也在不断发展。我相信我的问题主要源于 mysql 数据库，使用自制软件安装它（我相信默认情况下是最新版本）和 mysql2 gem 版本 Mr. Rappin 在什么时候用过12、0.3.11.

我更新了 Gemfile 以反映 mstwjs Gemfile.lock 文件中的 gem 版本：

source 'http://rubygems.org'

gem 'rails',   '3.2.7'
gem 'devise',  '2.1.2'

# Bundle edge Rails instead:
#gem 'rails',     :git => 'git://github.com/rails/rails.git'

gem 'mysql2',  '0.3.11'

# Asset template engines
group :assets do
  gem 'sass-rails',   '3.2.5'
  gem 'coffee-rails', '3.2.2'
  gem 'uglifier',     '1.2.6'
end

gem 'jquery-rails',       '2.0.2'
gem 'rails-backbone',     '0.7.2'
#gem 'sprockets_spacely'

# Use unicorn as the web server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger
# gem 'ruby-debug19', :require => 'ruby-debug'

group :development do
  gem 'powder',           '0.1.8'
  gem 'awesome_print',    '1.0.2'
  gem 'annotate',         '2.5.0'
end

group :test, :development do
  #gem 'guard-rails-assets'
  #gem 'guard-jasmine-headless-webkit'
  gem 'jasmine-headless-webkit', '0.8.4'
  gem 'jasmine',                 '1.2.0'
  gem 'jasminerice',             '0.0.9'
  gem 'rspec-rails',             '2.11.0'
end

然后

$ rbenv local use 1.9.3
$ brew install mysql2
$ gem install mysql2 -v ‘0.3.11’
$ bundle install

到目前为止一切顺利！当我尝试运行 mstwjs 设置生成器时：

$ rake mstwjs:setup --trace

我运行进入如下错误：

rake aborted!

有人知道我做错了什么吗？非常感谢您的见解。

我通过进行以下更改设法让回购工作：

# Gemfile
gem 'mysql2', '~> 0.3.20'

bundle update mysql2

# Create config/initializers/abstract_mysql2_adapter.rb
class ActiveRecord::ConnectionAdapters::Mysql2Adapter
    NATIVE_DATABASE_TYPES[:primary_key] = "int(11) auto_increment PRIMARY KEY"
end

bundle exec rake mstwjs:setup --trace

成功了。
