I've fixed.

BTW, do you use Debian GNU/Linux stretch? Ruby 2.3 is EOL. I recommend that you use Ruby 2.4 or later. Debian GNU/Linux buster provides Ruby 2.5.

Thanks for your advice. As far as I know, in order to use Ruby 2.4 or later, it is necessary to upgrade from Stretch to Buster. It is our future task.
