我刚刚用ruby启动了一个项目（在Windows上），当我运行'rails server'时，我有这个ince，essage：

  

C：\ Sites \ rails_projects \ first_app＆gt; 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:in require': cannot load such file -- mysql/mysql_api (LoadError) from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mysql-2.9.1-x8 6-mingw32/lib/mysql.rb:6:in救援'           来自C：/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/mysql-2.9.1-x8   6-mingw32 / lib / mysql.rb:2:in <top (required)>' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.5/ lib/bundler/runtime.rb:72:in require'           来自C：/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.5/   lib / bundler / runtime.rb：72：in block (2 levels) in require' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.5/ lib/bundler/runtime.rb:70:in each'           来自C：/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.5/   lib / bundler / runtime.rb：70：in block in require' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.5/ lib/bundler/runtime.rb:59:in each'           来自C：/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.5/   lib / bundler / runtime.rb：59：in require' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/bundler-1.3.5/ lib/bundler.rb:132:in require'           来自C：/Sites/rails_projects/first_app/config/application.rb:7:in <top (required)>' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.1 3/lib/rails/commands.rb:53:in require'           来自C：/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.1   3 / lib / rails / commands.rb:53:in block in <top (required)>' from C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.1 3/lib/rails/commands.rb:50:in点击'           来自C：/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/railties-3.2.1   3 / lib / rails / commands.rb:50:in <top (required)>' from script/rails:6:in require'           来自script / rails：6：in''

当然，我正在捣蛋。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'

我没有ruby代码文件（或者我有一个，当你创建一个新的轨道项目时生成的那个），因为我刚开始。

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：

不要同时包含sqlite3 gem和mysql gem。

  1. 删除现有的Gemfile.lock文件。

  2. 删除gem 'sqlite3'

  3. 将gem 'mysql'替换为gem 'mysql2', '~> 0.3.11'

  4. 运行bundle install然后重试。

    5. 另外，请确保在系统中安装了mysql。并将config/database.yml配置为使用development

    的mysql适配器

    修改
    将libmysql.dll从C:\Program Files\MySQL\MySQL version\bin（必须在那里，根据您的MySQL版本等）复制到C:/RailsInstaller/Ruby1.9.3/bin。
