expo 시작 오류

expo를 global로 설치하고 init까지 한 후

npm start를 했을 때 일단 아래처럼 에러가 발생합니다.

Unable to find expo in this project - have you run yarn / npm install yet?

-> 이건 npm install을 해서 해결 했습니다.

그런데 그 후에도 또 아래와 같은 에러가 발생합니다.

PS D:\Programming\study\Inflearn\FullStack\project\grab-market-mobile> npm start

> grab-market-mobile@1.0.0 start

> expo start

이건 어떻게 해결해야 하나요?
