I've been trying to fix this error, but I can't find a solution yet. I'm about to deploy a Rails application to production using nginx, puma, and capistrano, but I get an error when running this command line bundle exec cap production deploy:initial. Right after initializing 'PUMA:START' Top Task, my terminal throws an error message and exit the process.
shared/bundle/ruby/2.6.0/gems/puma-5.2.2/lib/puma/cli.rb:50:in `initialize': invalid option: --daemon (OptionParser::InvalidOption) puma stderr: Nothing written Tasks: TOP => puma:start (See full trace by running task with --trace)
I think this is caused by a wrong command line executed before which is:
00:00 puma:start
01 RBENV_ROOT=$HOME/.rbenv RBENV_VERSION=2.6.5 $HOME/.rbenv/bin/rbenv exec bundle exec puma -C /home/usr/myapp/shared/puma.rb --daemon
I have tried to find the way I could fix this by modifying the deploy process command, but I haven't found anything relevant.
I will leave my Capfile, deploy.rb, nginx.conf and gems, so you might have a better understanding of what's going wrong.

What Im suspecting is that the puma gem version ( probably > 5.0+) that you are using doesnt support --daemon option.
This was highlighted in the capistrano-puma documentation. The puma cli command line parser will throw error as --daemon wasn't one of the supported option. You can check your Gemfile.lock for your puma version to verify this.
In fact, the capistrano-puma doesn not stop you from using puma with version higher than 5.0. However, the gem user is responsible for the plugin compatibility requirement.
