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

gem 'sqlite3', '1.3.4' 
gem 'gravatar_image_tag', '0.1.0' 
gem 'will_paginate', '3.0.pre2' 
gem 'meta_search'

    gem 'rspec-rails', '2.0.1' 
    gem 'annotate-models', '1.0.4' 
    gem 'ruby-debug19', :require => 'ruby-debug' 
end 

group :test do 
    gem 'rspec', '2.0.1' 
    gem 'webrat', '0.7.1'

Answer 1

rake rails:updateを試してみてください。あなたのファイルが尋ねられたら上書きしますが、変更を見直して、保存したいファイルを保持しておくようにしてください（最終的に変更とあなたの結果をマージします）。

これは私がやったことであり、あなたにも同様のエラーが修正されました。
