当我尝试运行Heroku的错误运行的Heroku耙分贝时：迁移
heroku rake db:migrate
我收到以下错误：
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)
这里是我的Gemfile看起来是这样的：
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，我将“pg”添加到Gemfile中，但仍然抱怨。我有点失望，因为我不知道下一步该做什么..？
UPDATE 命令heroku run rake db:migrate导致相同的错误。
这里是我的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'
非常感谢你为你的帮帮我！

你是否运行'bundle install --without production'并在再次推送前检查生成的Gemfile.lock？ – iwasrobbed 2011-12-20 13:06:26
你有没有检查你的gemfile.lock？我敢打赌，这是以前的问题。现在，您可能需要运行“捆绑安装”，因为由于某种原因，您的gemfile.lock与heroku认为它应该有的不匹配。 – drhenner 2011-12-20 14:31:57
是的，我跑了那个命令。但由于我对RoR相当陌生，所以我不确定要注意什么。我有'pg'在规格下列出，并且在相关内容下收听。我如何检查Gemfile.lock的错误？当我输入'bundle install'时，我看不到'使用pg（0.12.0）'这行 - 这有点奇怪不是吗？ – MrBr 2011-12-20 15:20:18
