Ошибка запуска npm с помощью приложения create-react-app

У меня есть проект, который я не касался в течение 2 недель. Я беру его обратно, и теперь, когда я пытаюсь запустить npm start я получил эту ошибку.

> react-scripts start

sh: react-scripts: command not found

Я также пытаюсь клонировать мои репозитории и получать ту же ошибку. Если кто-то может дать мне способ узнать, что произойдет. Спасибо
