This is a bug for the current package of either create-react-native-app or one of the modules it consumes. We can fix this by addressing the error directly as-stated by providing an SDK version that's actually supported. Right now, v 25.0.0 is the latest.

Open the app.json and change this line (it might be higher than v 27 by the time you read this):
"sdkVersion": "27.0.0"

to this line:
"sdkVersion": "25.0.0"

Then from that directory, run npm install to re-install the correct SDK.
