React Native Undefined is not an object(evaluating ‘_react2.PropTypes.func’)

我原来的写法

import React,
{ Component, PropTypes } from
'react';

export default class CommonTitle
extends Component {
    render() {
        return (
          …
        )
    }

 }

CommonTitle.propTypes = {
    onTitleClick: PropTypes.func.isRequired
}
PropTypes 放在了react 中引入，但是还是出错
Undefined is not an object(evaluating ‘_react2.PropTypes.func’)

正确写法：

import React,
{ Component } from 'react';
import PropTypes from
'prop-types';
把PropTypes 从prop-types 中引入
