Rake error with rails 3.2.9

Question

我剛剛從3.2.8升級到Linux Mint 14和Rails 3.2.9。現在，我得到這個錯誤，當我運行rake db:create

rake aborted! 
undefined method `values_at' for "MySQL. Versions 4.1 and 5.0 are recommended.":String 
Tasks: TOP => db:create 

我的Gemfile看起來像這樣：

source 'https://rubygems.org' 

gem 'rails', '3.2.9' 
gem 'execjs' 
gem 'therubyracer' 


# Bundle edge Rails instead: 
# gem 'rails', :git => 'git://github.com/rails/rails.git' 

gem 'mysql2' 


# 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'

難道你忘了更新一些依賴？ 嘗試運行：

$ bundle outdated 

，並檢查是否需要更新其他寶石....
