配置Rails 4，MongoDB，黄瓜，水豚

Question

我目前正在设置我的第一个Mongodb，Rails 4环境，并且需要在运行bundle安装之前配置gem。这是我的宝石文件。

source 'https://rubygems.org' 

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails' 
gem 'rails', '4.0.1' 

# User mongoid for database. 
gem 'mongoid', github: 'mongoid/mongoid' 

# Use SCSS for stylesheets 
gem 'sass-rails', '~> 4.0.0' 

# Use Uglifier as compressor for JavaScript assets 
gem 'uglifier', '>= 1.3.0' 

# Use CoffeeScript for .js.coffee assets and views 
gem 'coffee-rails', '~> 4.0.0' 

# See https://github.com/sstephenson/execjs#readme for more supported runtimes 
# gem 'therubyracer', platforms: :ruby 

# 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', '~> 1.2' 

group :doc do 
# bundle exec rake doc:rails generates the API under doc/api. 
gem 'sdoc', require: false 
end 

group :test do 
    gem 'cucumber-rails', :require => false 
    gem 'capybara' 
    #database_cleaner is not required, but highly recommended 
    gem 'database_cleaner' 
end 

看来Mongo不会安装，因为我找不到Mongo：Config文件。通过运行以下命令生成

配置文件：

rails g mongoid:config

请阅读mongoid文档，这是相当不错的。
