module appregistry is not a registered callable module (calling runApplication) 模块appregistry不是一个已注册的可调用模块（调用runApplication）。

我完全找不到让react-navigation工作的方法。我从互联网上复制了一些可行的示例，但它们似乎也无法运行。有人可以告诉我我做错了什么吗？\n我使用的版本是：\n node: 8.9.4\n react: 16.3.0-alpha.1\n react-native: 0.54.0\n react-navigation: ^1.4.0\n这是index.js的代码：\n

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View
} from 'react-native';
import {
  TabNavigator,
  StackNavigator
} from 'react-navigation';
import Home from './first';
import Homes from './second';
export default class demoApp extends Component {
  render() {
    return (
      
    );
  }
}
export const SimpleNavigation = StackNavigator({
  Home: { 
    screen: Home,
    header: { visible: false },
    navigationOptions: {
      title: 'Home',
      header: null
    },
  },
  Homes: { 
    screen: Homes,
    navigationOptions: {
      title: 'second'
    },
  },
},{});

\n这是first.js的代码：\n

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View,
  Image,
  TextInput,
  Button,
  TouchableHighlight
} from 'react-native';
export default class Home extends Component {
    constructor(props){
        super(props);
        this.state = {zipCode: ''}
    }
    navigate = (zipCode) => {
        this.props.navigation.navigate('Search', zipCode);
    }
    render() {
        return (
            
                
                    An application to do things
                     this.setState({zipCode})}
                        >
                    
                
                
                     this.navigate(this.state.zipCode)}>
                        
                            Search
                        
                    
                
            
        );
    }
}

\n我似乎无法使其运行。我也尝试了很多其他教程，但都没有成功。我做错了什么？
