失败而创建的轨道新的应用程序

Question

安装mysql2在使用MySQL作为数据库中创建Rails应用程序，我收到以下错误

... 
... 
Installing mysql2(0.3.13) 
Gem:Installer::ExtensionBuilderError: ERROR: Failed to build gem native extension 
C:/RailsInstaller/Ruby1.9.3/bin/ruby.exe extconf.rb 
checking for rb_thread_blocking_region 
checking for rb_wait_for_single_fd<>... yes 
checking for rb_has_dup<>... yes 
checking for rb_intern3<>... yes 
***extconf.rb failed *** 
Could not create Makefile due to some reasons, probably lack of necessary libraries and/or headers. Check the mkmf.log for more details. You may need configuration options 

不过，如果我使用默认的SQLite数据库，是没有问题的

My OS & MySQL information 
OS:Winodows 8 64bit 
MySQL: 5.6(64 bit)

不幸的是mysql2 gem有问题，你现在必须安装mysql gem，在你的config/database.yml和gemfile中修改mysql2/mysql后执行bundle安装，希望能够清楚。
