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

打开当前目录，

npm install react-native-deprecated-custom-components --save

import {Navigator} from 'react-native-deprecated-custom-components';

修改后代码如下

'use strict';
import React,{Component} from 'react';
import  {
  AppRegistry,} from 'react-native';
import {Navigator} from 'react-native-deprecated-custom-components';

        onPress={this.props.onPress}>
        <Text style={styles.buttonText}>{this.props.text}</Text>
      </TouchableHighlight>
    );
  }
}
class NavMenu extends React.Component {
  render() {
    return (
      <View style={styles.scene}>
        <Text style={styles.messageText}>{this.props.message}</Text>
        <NavButton
