Почему json-server не работает должным образом?

Посли запуска npm с установкой json-server было введена команда json-server db.json на что терминал выдал 'bash: json-server: command not found'(Пробовал устанавливать json-server глобально не помогло)

This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.

See `npm help json` for definitive documentation on these fields
and exactly what they do.

Use `npm install <pkg>` afterwards to install a package and
save it as a dependency in the package.json file.

Press ^C at any time to quit.
