Question

我试图开始通过Noel Rappin's非常有前途的＆＃34; Master Space and Time with JavaScript.＆＃34;一个障碍源于the code最后一次更新于2012年9月，并且生态系统已经发展。我相信我的问题主要源于mysql数据库，用homebrew安装它（我相信默认最新版本）和rappin先生在12,0.3.11中使用的mysql2 gem版本。

我已更新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！当我尝试使用：

运行mstwjs设置生成器时

$ rake mstwjs:setup --trace

我遇到以下错误：

任何人都有任何想法，我做错了什么？非常感谢您的见解。

我设法通过进行以下更改来使回购工作：

# 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

搞定了。
