Vagrantファイルでこのように転送ポートを3000に設定して、Vagrantで新しいRailsアプリを起動して実行しました
config.vm.forward_port 3000, 3000
サーバーをシャットダウンしてvagrantを終了した後、「127.0.0.1への接続が閉じられました」という出力が表示されましたが、Vagrantを使用せずにRailsアプリを起動しようとすると、

Google検索で、これを行う必要があると言われました
ps ax | grep ruby
その後、プロセスを強制終了しますが、grepによって返された番号のプロセスがないと言われました。
michael$ ps ax | grep ruby
3604 s001 R+ 0:00.00 grep ruby
michael$ kill -9 3604
-bash: kill: (3604) - No such process
これが Vagrant の使用に関連している場合、問題を解決する方法はありますか?
