我是新来的，所以如果我的帖子不符合标准，我深表歉意。
我正在做Mike Hartl的Rails教程，在第7章末尾，我对heroku的推送无效。 Heroku州
“应用程序错误应用程序和页面中发生错误
无法送达。请稍后重试。
如果您是应用程序所有者，请检查您的日志以获取详细信息。”
它在本地可以正常工作，我不确定是什么原因造成的，因为在第六章末尾它仍然可以正常工作。我以为这是我的gem文件中的内容，但我注释掉了添加的两个gem，它做了同样的事情。

看起来我缺少什么吗？自从取出Puma宝石以来，我取出了Procfile，但这似乎没有什么不同。不知道我是否还需要包括其他文件...
任何帮助将不胜感激。谢谢！
最佳答案
是的，看来您缺少config /文件夹中的puma配置。
No such file or directory - config/puma.rb (Errno::ENOENT)
从heroku文档中：
https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server#config
在config / puma.rb或您选择的路径中为Puma创建一个配置文件。对于简单的Rails应用程序，我们建议以下基本配置：
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
