Expo issue with Metro Bundle

Today, I decided to create my first app using Expo but when I type “expo start” this is the error that I got: npm start

@ start /Users/kevin/Native/first-project

expo start

Starting project at /Users/kevin/Native/first-project

Expo DevTools is running at http://localhost:19002

Opening DevTools in the browser… (press shift-d to disable)

Could not get status from Metro bundler. connect ECONNREFUSED 127.0.0.1:19001

Connecting to Metro bundler failed.

Set EXPO_DEBUG=true in your env to view the stack trace.

npm ERR! code ELIFECYCLE

npm ERR! errno 1

npm ERR! @ start: expo start

npm ERR! Exit status 1

npm ERR!

npm ERR! Failed at the @ start script.

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:

Can someone help me?
