简报：我一直试图将我的博客部署到heroku上一周没有运气。我已经联系了Heroku支持，他们几乎告诉我在stackoverflow上发布日志。所以我在这里。
我很确定它与postgreSQL有关，但我可能错了。无论如何这里是代码库：www.github.com/apane/blogit_blog。
Heroku记录在下面。
Gemfile提供了很好的衡量标准：
source 'https://rubygems.org'
gem 'rails', '3.2.13'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'blogit', '0.8.0'
gem "will_paginate", "~> 3.0.4"
gem 'devise'
# Gems used only for assets and not required
# in production environments by default.
group :production do
gem 'pg'
gem "unicorn", "~> 4.6.2"
end
group :development, :test do
gem 'pg'
gem "unicorn", "~> 4.6.2"
end
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'

Please install the sqlite3 adapter: `gem install activerecord-sqlite3-adapter` (sqlite3 is not part of the bundle. Add it to Gemfile.)

看起来你可能在开发中使用sqlite。
你可以在你的gemfile中尝试这个而不是你拥有的吗？
group :development, :test do
gem 'sqlite3'
gem "unicorn", "~> 4.6.2"
end
然后通常捆绑安装并再次运行迁移。

错误Please install the sqlite3 adapter: 'gem install activerecord-sqlite3-adapter'表示您的本地环境配置为运行SQLite，但未安装SQLite。该消息引用了activerecord-sqlite3-adapter gem，但是在Gemfile中，在完全集成的Rails环境中，您只需将sqlite3捆绑到您想要运行的环境（可能是开发和测试，因为你的作品是使用Postgres的Heroku。
使用以下内容替换Gemfile中的group :development, test块：
group :development, :test do
gem 'sqlite3'
gem "unicorn", "~> 4.6.2"
end

请记住，Heroku使用配置属性DATABASE_URL而不是database.yml文件来连接到您的数据库。确保它已设置。
heroku config：set DATABASE_URL = sqlite3：// bb06ca765fb123：71b6dabc@us-cdbr-east-04.cleardb.com/heroku_703eded6aebc123？reconnect = true
