React Native: Unable to load image

I am writing a simple iOS program to show an image using React Native.

'use strict';

var React = require('react-native');
var {
  Image
} = React;

var styles = React.StyleSheet.create({

  base: {
    height: 400,
    width: 400 
}
});

class SimpleApp extends React.Component {
  render() {
    return (
    <Image
    style={styles.base}
    source={require('image!k')}
    //source={{uri: 'http://news.xinhuanet.com/world/2015-05/09/127782089_14311512601821n.jpg'}}
      /> 
    )
  }
}

React.AppRegistry.registerComponent('SimpleApp', () => SimpleApp);

      

        
        
        
      

    

But I got a message from the iPad screen:

"Failed to print error:","'undefined' is not an object (evaluating 'stackString.split')"

      

        
        
        
      

    

When I change the code to use image url

//source={require('image!k')}
source={{uri: 'http://news.xinhuanet.com/world/2015-05/09/127782089_14311512601821n.jpg'}}

      

        
        
        
      

    

I only get a red rectangular border.

When I use another js file everything works well. "Hello World" can be displayed on the iPad screen.

'use strict';

var React = require('react-native');
var {
  Text,

} = React;


class SimpleApp extends React.Component {
  render() {
    return (

        <Text>Hello World</Text>

    )
  }
}

React.AppRegistry.registerComponent('SimpleApp', () => SimpleApp);
