Webpack не стартует дев-сервер

Приветствую всех!

Начал разбираться в реакте, качнул курс для порядка... там есть все конфиги, и, судя по видео, у автора все работает нормально, но у меня почему-то не стартуется вебпак-дев-сервер.

Конфиг package.json:

Ошибки по запуску:

> test-proj@1.0.0 dev /WebServer/react.local

> test-proj@1.0.0 start /WebServer/react.local
> webpack-dev-server --progress --inline --hot

Гуглил, пробовал по разному решить проблему, но не победил. Повторюсь, этой теме новичок. Подскажите, в чем может быть проблема?
