install react-native-navbar

[cyaxares]

I installed react-native-navbar, But while using showed error like pic:

I checked and It existed before , I also removed it and installed by npm

Code:

'use strict';

import React, { Component } from 'react';
import{
  View,
  Text,
  StyleSheet

} from 'react-native';
import NavigationBar from 'react-native-navbar';

class Header extends Component {
    render() {
      const rightButtonConfig = {
        title: 'Next',
        handler: () => alert('hello!')
      };
      const titleConfig = {
        title: 'Hello, world',
      };

      return (
        <View>
          <NavigationBar
            title={titleConfig}
            rightButton={rightButtonConfig} />
        </View>
      );
    }
}
export default Header;

what's the problem?
