下面是Procfile

在配置

web: bundle exec puma -C config/puma.rb 

彪馬配置文件/ puma.rb

workers Integer(ENV['WEB_CONCURRENCY'] || 2) 
threads_count = Integer(ENV['MAX_THREADS'] || 5) 
threads threads_count, threads_count 

preload_app! 

rackup  DefaultRackup 
port  ENV['PORT']  || 3000 
environment ENV['RACK_ENV'] || 'development' 

on_worker_boot do 
    # Worker specific setup for Rails 4.1+ 
    # See: https://devcenter.heroku.com/articles/deploying-rails- 
    # applications- with-the-puma-web-server#on-worker-boot 
    ActiveRecord::Base.establish_connection 
end 

我甚至嘗試通過去除PUMA，以爲它會在使用WEBrick運行部署，但仍然美洲獅的錯誤被拋出。

Answer 1

錯誤與彪馬不同。錯誤得到執行後解決

heroku run rake db:migrate
