"Ошибка: пожалуйста, установите пакет pg вручную" при попытке запустить "npm run serve:dev"?

Я пытаюсь запустить приложение с помощью скрипта npm run serve: dev, но выдает ошибку Ошибка: Пожалуйста, установите пакет pg вручную при попытке запустить npm run serve: dev

Я уже пробовал npm установить -g pg','npm установить -g pg-hstore
