我正在关注Ruby on Rails教程，目前正在执行此步骤： http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec-heroku_setup
我不确定我做错了什么，但我相信它可能与Gemfile和PostgreSQL有关。

Bundler will do a full resolve so native gems are handled properly.
This may result in unexpected gem versions being used in your app.
In rare occasions Bundler may not be able to resolve your dependencies at

这就是发生的事情。我的gemfile如下：
source 'https://rubygems.org'
ruby '1.9.3'
gem 'rails', '3.2.16'
group :development do
gem 'sqlite3', '1.3.5'
end
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '3.2.5'
gem 'coffee-rails', '3.2.2'
gem 'uglifier', '1.2.3'
end
gem 'jquery-rails', '2.0.2'
group :production do
gem 'pg', '0.12.2'
end
我试图在其他地方提出一些建议，但似乎都没有效果。我盲目地输入了heroku run rake db:create和heroku run rake db:migrate，两者都提供了错误rake aborted!

听起来你可能没有添加Heroku Postgres附加组件。尝试从命令行运行heroku addons:add heroku-postgresql或进入Heroku仪表板并从其GUI启用插件
