在Rails 3中獲取Gem :: Ext :: BuildError 3

Question

我想用Mongodb.I插入兩個gem（ie-gem'mongoid'，'〜> 3.0.1'和gem'bson_ext '），當運行bundle install時，我得到以下錯誤。

ERROR1：

Gem::Ext::BuildError: ERROR: Failed to build gem native extension. 

    C:/Ruby193/bin/ruby.exe -r ./siteconf20150509-6132-1esd4mr.rb extconf.rb

An error occurred while installing bson_ext (1.12.1), and Bundler cannot 
continue. 
Make sure that `gem install bson_ext -v '1.12.1'` succeeds before bundling. 

按照該指令被上面給出我再次運行gem install bson_ext -v '1.12.1'，但我得到了下面的錯誤。

誤差2：

ERROR: Error installing bson_ext:

的Gemfile：

source 'https://rubygems.org' 

gem 'rails', '3.2.19' 

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

gem 'sqlite3' 


# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails', '~> 3.2.3' 
    gem 'coffee-rails', '~> 3.2.1' 

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

    gem 'uglifier', '>= 1.0.3' 
end 

gem 'jquery-rails' 

# To use ActiveModel has_secure_password 
# gem 'bcrypt-ruby', '~> 3.0.0' 

# To use Jbuilder templates for JSON 
# gem 'jbuilder' 

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

# Deploy with Capistrano 
# gem 'capistrano' 

# To use debugger 
# gem 'debugger' 
gem 'mongoid', '~> 3.0.1' 
gem 'bson_ext' 

請幫我解決這個錯誤。
