真的坚持第2.5步：部署（推送）到heroku - （http://installfest.railsbridge.org/installfest/deploy_a_rails_app）。我按要求完成了。然而，预期结果并不匹配。即使我尝试过类似帖子的所有解决方案，问题仍然存在。我已将SQLite更改为“pg”。安装postgresq1。但无济于事。检测到SQLite gems，我无法在文件中找到它们。请原谅，我现阶段缺乏理解。

请检查Gemfile.rb，请把你的＆＃39; sqlite3＆＃39;在像这样的开发组。
group :development do
gem 'sqlite3'
end
group :production do
gem 'pg' # Use postgresql as the database for Active Record got heroku
gem 'rails_12factor'
end
请删除您应用程序中的Gemfile.lock，请再次进行捆绑安装或捆绑更新。 并将您的代码推送到存储库并完成提交。使用新的Gemfile.rb和Gemfile.lock也提交。
然后最后做
git push heroku master
