當我嘗試運行Heroku的錯誤運行的Heroku耙分貝時：遷移
heroku rake db:migrate
我收到以下錯誤：
rake aborted! Please install the postgresql adapter:
gem install activerecord-postgresql-adapter(pg is not part of the bundle. Add it to Gemfile.) Tasks: TOP => db:migrate => db:load_config (See full trace by running task with --trace)
這裏是我的Gemfile看起來是這樣的：
group :production do
gem 'pg'
end
group :development, :test do
gem 'turn', '0.8.2', :require => false
gem 'sqlite3', '1.3.5'
end
因此，我將「pg」添加到Gemfile中，但仍然抱怨。我有點失望，因爲我不知道下一步該做什麼..？
UPDATE 命令heroku run rake db:migrate導致相同的錯誤。
這裏是我的Gemfile：
source 'http://rubygems.org'
gem 'rails', '3.1.3'
group :production do gem 'pg', '0.12.0' end
group :development, :test do # Pretty printed test output gem 'turn', '0.8.2', :require => false gem 'sqlite3', '1.3.5' end
# Bundle edge Rails instead: # gem 'rails', :git => 'git://github.com/rails/rails.git'
# Gems used only for assets and not required # in production environments by default. group :assets do gem 'sass-rails', '~> 3.1.5' gem 'coffee-rails', '~> 3.1.1' gem 'uglifier', '>= 1.0.3' end
gem 'jquery-rails'
# To use ActiveModel has_secure_password # gem 'bcrypt-ruby', '~> 3.0.0'
# Use unicorn as the web server # gem 'unicorn'
# Deploy with Capistrano # gem 'capistrano'
# To use debugger # gem 'ruby-debug19', :require => 'ruby-debug'
非常感謝你爲你的幫幫我！

你是否運行'bundle install --without production'並在再次推送前檢查生成的Gemfile.lock？ – iwasrobbed 2011-12-20 13:06:26
你有沒有檢查你的gemfile.lock？我敢打賭，這是以前的問題。現在，您可能需要運行「捆綁安裝」，因爲由於某種原因，您的gemfile.lock與heroku認爲它應該有的不匹配。 – drhenner 2011-12-20 14:31:57
是的，我跑了那個命令。但由於我對RoR相當陌生，所以我不確定要注意什麼。我有'pg'在規格下列出，並且在相關內容下收聽。我如何檢查Gemfile.lock的錯誤？當我輸入'bundle install'時，我看不到'使用pg（0.12.0）'這行 - 這有點奇怪不是嗎？ – MrBr 2011-12-20 15:20:18
