在 Rails 应用程序上工作并在我的 Mac OSX 10.6.8 上缺少一些软件
Working on a Rails app and missing some software on my Mac OSX 10.6.8
我正在关注 this guide as part of a web development curriculum, so I'm sure I'll fully understand what each part does later on, but for now I'm just doing what it says and figuring out everything I can based on what I know. The previous chapter (creating an app) was a success, but now I've stumbled against this instruction。我无法编辑该行，因为它不存在。这是 Gemfile，在 TextEdit 中查看：
source 'https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.1'
# Use jdbcsqlite3 as the database for Active Record
gem 'activerecord-jdbcsqlite3-adapter'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 5.0'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .coffee assets and views
gem 'coffee-rails', '~> 4.1.0'
# See https://github.com/rails/execjs#readme for more supported runtimes
gem 'therubyrhino'
# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 2.0'
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', '~> 0.4.0', group: :doc
# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'
# Use Unicorn as the app server
# gem 'unicorn'
# Use Capistrano for deployment
# gem 'capistrano-rails', group: :development
group :development, :test do
end
# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
应用程序运行良好，服务器运行良好（尽管不必 运行 所以我想这并不是那么重要）。该指南很可能有问题，但它是什么？现在构建它有什么意义吗？还是我应该继续学习并在我对 Rails 和 Ruby 本身有了更多了解后再回来使用它？
编辑： 我在 Gemfile 和 运行 bundle install 的末尾添加了行（感谢@Antarr Byrd！）但是我收到一条错误消息。为了以防万一，我发布了整个日志：

如果你的数据库是sqlite那么你需要添加

end
如果是 mysql 只需将 gem 'sqlite3' 替换为 gem 'mysql2'

2) 您 运行 使用 JRuby 1.7，这对于第一个应用程序来说是一个有点奇怪的选择。看看你说你正在关注的 Railsbridge 文档，他们让你使用 Ruby 2.2，这是一个更常见的平台。我会按照他们的指南 Step 7 安装 2.2 和 RVM，然后再试一次。
