我刚刚用 ruby 开始一个项目（在 Windows 上），当我运行 'rails server' 时，我有这个 ince ，essage：
C:\Sites\rails_projects\first_app>rails 服务器 C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mysql-2.9.1-x86-mingw32/lib /mysql.rb:6:在

当然，我错过了什么。这是我的 Gemfile：来源“ https://rubygems.org ”
gem 'rails', '3.2.13'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'bundler'
gem 'sqlite3'
gem 'mysql'
gem 'geocode'
gem 'gmaps4rails'
gem 'railties'
# 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'
因为我刚刚开始，所以我没有 ruby 代码文件（或者我有一个，当你创建一个新的铁路项目时生成的那个）。
提前致谢，
感谢您的快速回答，但不幸的是我遇到了同样的错误：
