如何在最新版本的React Native中使用Navigator？

import React, { Component } from 'react'; 
import { 
    AppRegistry, 
    StyleSheet, 
    Text, 
    View, 
    Navigator 
} from 'react-native'; 

import Component5 from './app/components/component5/component5.js'; 
import Component6 from './app/components/component6/component6.js'; 

export default class myproject extends Component { 
    renderScene(route, navigator){ 
    switch(route.id){ 
     case 'component5': 
     return(<Component5 navigator={navigator} title="component5" />) 
     case 'component6': 
     return(<Component6 navigator={navigator} title="component6" />) 
    } 
    } 

    render() { 
    return (
     <Navigator 
     initialRoute={{id:'component5'}} 
     renderScene={this.renderScene} 
     configureScreen={(route, routeStack) => Navigtator.SceneConfigs.FloatFromBottom} 
     /> 
    ); 
    } 
} 


AppRegistry.registerComponent('myproject',() => myproject);

當我運行它時，它拋出這個錯誤：
