React native Undefined 不是一个对象（评估'_react3.default.PropType.shape'）

Question

由于这种情况，我正在使用 React-native 学习，我想为 IOS 和 Android 创建导航，实际上，我遇到了一个错误

错误：React native Undefined is not an object(evalating'_react3.default.PropType.shape')

我的开发环境

• 操作系统：MACOS Sierra
• Clie：react-native-cli：2.0.1
• 反应原生版本：反应原生：0.49.3

我关注react-native官方tutorial

App.js

import React, { Component } from 'react';
import {Platform, StyleSheet, Text, View} from 'react-native';
import Navigator from 'react-native-deprecated-custom-components';
import MyScene from './src/components/navigation/MyScene';



const instructions = Platform.select({
  ios: 'IOS: Press Cmd+R to reload,\n' +
    'Cmd+D or shake for dev menu',
  android: 'Android : Double tap R on your keyboard to reload,\n' +
    'Shake or press menu button for dev menu',
});
export default class App extends Component {
    render() {
        return (

            <Navigator initialRoute={{ title: 'My Initial Scene', index: 0 }}
                renderScene={(route, navigator) =>
                    <MyScene
                        title={route.title}

                        // Function to call when a new scene should be displayed
                        onForward={() => {

                            const nextIndex = route.index + 1;
                            navigator.push({
                                title: 'Scene ' + nextIndex,
                                index: nextIndex,
                            });
                        }}

                        // Function to call to go back to the previous scene
                        onBack={() => {
                            if (route.index > 0) {
                                navigator.pop();
                            }
                        }}
                    />
                }
            />
        )
    }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  welcome: {
    fontSize: 50,
    textAlign: 'center',
    margin: 10,
  },
  instructions: {
    textAlign: 'center',
    color: '#333333',
    marginBottom: 5,
  },
});

MyScene.js

import React, { Component, PropTypes } from 'react';
import { View, Text, TouchableHighlight } from 'react-native';

export default class MyScene extends Component {
    render() {
        return (
            <View>
                <Text>Current Scene: {this.props.title}</Text>
                <TouchableHighlight onPress={this.props.onForward}>
                    <Text>Tap me to load the next scene</Text>
                </TouchableHighlight>

                <TouchableHighlight onPress={this.props.onBack}>
                    <Text>Tap me to go back</Text>
                </TouchableHighlight>
            </View>
        )
    }
}

MyScene.propTypes = {
    title: PropTypes.string.isRequired,
    onForward: PropTypes.func.isRequired,
    onBack: PropTypes.func.isRequired,
};

检查你的反应版本， 如果版本大于 16，则 propTypes 位于名为 prop-types 的新包中
