react native yarn start using expo is not working

I'm trying to run the expo but nothing happens.

My try:

➜  expoTest git:(master) ✗ yarn start
yarn run v1.22.4
$ expo start
Starting project at /Users/seungjune/project/tutorial/expoTest

When I tried npm start or yarn start or expo-cli start, it still not working after the message as follows

Starting project at /Users/seungjune/project/tutorial/expoTest

I found error after starting meesage as follows
