Check the readme file,looks like create-react-native-app is replaced with new expo-cli. Just figured it.

[prog1dev]

@yolossn Thanks. But readme also says

The create-react-native-app command is provided for backwards compatibility.

So it should work and I think its worth to open an issue.

Also getting started section in facebook RN docs have old way of creating RN app

Yes, backward compatibility must be insured ! As you said, even the React Native documentation is not up to date.
A new developer on React Native types 2 lines of command and is already blocked, I understand why many beginners are giving up.
We create a React JS app with:
create-react-app myapp
and React Native app with:
expo init myapp
So logical ¯_(ツ)_/¯

Same issue here. It took me several days to figure out what the issues were. Make sure you're using create-react-native-app @ v2. I got the UnhandledPromiseRejectionWarning: when trying to use anything below the new v2. Then follow the steps I've outlined in the issue linked below to fix all of the other bugs/issues that were introduced when they merged create-react-native-app with Expo a few days ago. Mopst of these other issues are relevant only if you eject the app.

See this issue for fixes

@caseychoiniere Thanks, I updated my CRNA CLI to v2 and everything is working.
