Question

我無法連接mysql到rails，我試圖修改database.yml和gemfile，但沒有任何作品。請幫助。

Rails環境配置

git:

ruby: 
    bin:  C:/RailsInstaller/Ruby1.9.2/bin/ruby.exe 
    version: ruby 1.9.2p290 (2011-07-09) [i386-mingw32] 

rails: 
    bin:  C:/RailsInstaller/Ruby1.9.2/bin/rails.bat 
    version: Rails 3.1.1 

過程

C:\Sites>cd demo 

C:\Sites\demo>rake db:migration 
rake aborted!
