hi, I use create-react-native-app create a new CRNA project, and did not modify anything. But when I run ‘npm start’ or ‘npm run android’, it all gives below error:
undefiend is not an object（evaluating nativeVersion.major）
Help Please! Here is ‘package.json’:
“dependencies”: {
“expo”: “^22.0.0”,
“react”: “16.0.0-beta.5”,
“react-native”: “^0.49.5”
}
I am also getting the same error in android after upgrading a detached app from Expo v21 to v22 today.
I fixed my issue by installing the correct version of React as mentioned in the SDK 22 release notes. I had React v16.0.0 instead of v16.0.0-beta.5 
But it is a bit odd that I had this error in Android only after upgrading to SDK 22 since I had React 16.0.0 with SDK 21.
