Element type is invalid: expected a string (for built-in components) or a class/function but got: object.

I know this question has been asked for a number of times, but solutions I read don't work out in my case. My codes are super simple and straightforward:

// Import a library to help create a component
import React from 'react';
import { AppRegistry, Text } from 'react-native';

//Only access text and AppRegistry from React-native lib

//Create a component
const App = () => (
    <Text>Some Text</Text>
);

//Render it to the device
AppRegistry.registerComponent('myapp2_albums', () => App);

I am using expo to develop ios app. It keeps showing Element type is invalid: expected a string (for built-in components) or a class/function but got: object. You likely forgot to export your component from the file it's defined in.

Check the render method of ‘AwakeInDevApp’

Any insight would be appreciated:)

React native can sometimes be picky about wrapping your fields within a view and give it a flex of 1. 

import React from 'react';
import { AppRegistry, Text } from 'react-native';

//Only access text and AppRegistry from React-native lib

//Create a component
  export default const App = () => {
  return (
   <View style={{ flex: 1}}>
       <Text>Some Text</Text>
   </View>
  );
};

//Render it to the device
AppRegistry.registerComponent('myapp2_albums', () => App);
