3 個解決方案

您的Gemfile中一定不能包含pg，這使我認為您的gemfile中可能缺少部署特定的內容。 在您的gemfile中找到sqlite3或等效的開發數據庫gem並進行重組，這通常是這樣完成的。 Heroku自動尋找：production環境並加載適用的配置。
group :development do
# Access an IRB console on exception pages or by using <%= console %> anywhere in the code.
gem 'web-console', '>= 3.3.0'
gem 'sqlite3'
end
group :production do
gem 'pg'
gem 'rails_12factor'
gem 'letsencrypt-rails-heroku'
end
當架構更改時忘記遷移數據庫時，有時還會收到該錯誤。 您可以使用heroku run rake db:migrate來做到這一點。

嘗試重新啟動測功機。
heroku ps:restart
或者嘗試簡單地heroku restart
說明： Devcenter Heroku
通過幫助的Heroku部署錯誤H10（應用程序崩潰），這也可以

您需要更新問題中的日志，以使它們更具可讀性。 使用Postgresql時，需要將pg添加到Gemfile中。
The gem is not loaded. Add `gem 'pg'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).(Gem::LoadError)
將Rails應用部署到Heroku時出錯
