失敗而創建的軌道新的應用程序

Question

安裝mysql2在使用MySQL作爲數據庫中創建Rails應用程序，我收到以下錯誤

... 
... 
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 

不過，如果我使用默認的SQLite數據庫，是沒有問題的

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

不幸的是mysql2 gem有問題，你現在必須安裝mysql gem，在你的config/database.yml和gemfile中修改mysql2/mysql後執行bundle安裝，希望能夠清楚。
