No Procfile detected using default webserver (webrick)

I am trying to deploy my Ruby on Rails application. Here is the error on my command line:

 ###### WARNING:
remote:        No Procfile detected, using the default web server (webrick)
remote:        https://devcenter.heroku.com/articles/ruby-default-web-server

I tried following the advice in No Procfile Detected Using Default Web Server ", but it didn't help.

At the top of the information given in the comments you have this error because in yours Procfile

you have:

web: bundle exec rails server -p $PORT

Thus, the default will be used webrick

.



To remove this warning, you must use another web server such as Unicorn, Thin, or Puma.

Heroku now advocates using Puma (see Changelog ).

And to get started with Puma and Heroku, you can head over to the Deploy Rails Applications with Puma Web Server article on the Heroku website.

In my case, I ignored the Procfile in .gitignore, due to other online manual pages. At that time, they instructed to hide the files declaring environment variables containing information about the mail account. So check your .gitignore file and delete if you see a Procfile in it.
