Heroku Open “Puma Port 5000 Already In Use” Rails
问题 When I Control-C to quit "Heroku Open" (the Heroku Toolbar server command). I'm unable to restart. I receive this error: /vendor/bundle/gems/puma-2.14.0/lib/puma/binder.rb:233:in `initialize': Address already in use - bind(2) for "0.0.0.0" port 5000 (Errno::EADDRINUSE) web.1 | s/vendor/bundle/gems/puma-2.14.0/lib/puma/cluster.rb:304:in `run' Is their a "correct" way to shut down the Heroku Toolbar local rails server in order to avoid this problem? 回答1: The only method I've used that works to
