React Native报错undefined is not an object（evaluating ‘_reactnative.propTypes’）解决办法...

原程序是这样写的，然后一直出现错误，找不到PropTypes，

 

import React,{Component } from 'react';
import {
    View,
    Text,
    Image,
    TouchableWithoutFeedback,
    PropTypes,
    StyleSheet
} from 'react-native';

替换成下面的代码就可以成功解决错误。。

 

    import React,{Component,PropTypes} from 'react';  import {      View,      Text,      Image,      TouchableWithoutFeedback,      //PropTypes,      StyleSheet  } from 'react-native';
import React,{Component,PropTypes} from 'react';
import {
    View,
    Text,
    Image,
    TouchableWithoutFeedback,
    //PropTypes,
    StyleSheet
} from 'react-native';
