Observed Behavior

What actually happened when you performed the above actions?

If there's an error message, please paste the full terminal output and error message in this code block:

Helios:k10 kimon$ npm run eject

> [email protected] eject /Users/kimon/Development/k10
> react-native-scripts eject


We didn't find any uses of the Expo SDK in your project, so you should be fine to eject to
"Plain" React Native. (This check isn't very sophisticated, though.)

We strongly recommend that you read this document before you proceed:
  https://github.com/react-community/create-react-native-app/blob/master/EJECTING.md

Ejecting is permanent! Please be careful with your selection.

? How would you like to eject from create-react-native-app? ExpoKit: I'll create or log in with an Expo account to use React Native and the Expo SDK.

An Expo account is required to proceed.

? It appears you're already logged in to Expo as kinergy, would you like to continue with this account? Yes, continue as kinergy.

Thanks for pointing this out @kinergy! I tried the exact repro steps and had the same error

[kinergy]

Same result in Node 6...

@kinergy - indeed, this has nothing to do with the node version -- we changed the format of the iOS template that is downloaded and it wasn't accounted for yet because we are slightly delayed on a new create-react-native-app release due to @dikaiosune and I being tied up with React Europe.

We'll have a fix for this today. Also cc @terribleben

@kinergy now that the fix is out, updating your react-native-scripts to a newer version (ex 0.0.40) should fix the problem
