新建了一个 

    class Person extends React.Component {
        super
        render () {
            return (
                <ul>
                    <li>姓名：{this.props.name}</li>
                    <li>性别：{this.props.sex}</li>
                    <li>年龄：{this.props.age}</li>
                </ul>
            )
        }
    }
    Person.defaultProps = {
        sex: \'男\',
        age: 18
    }
    Person.prototype = {
        name: PropTypes.string.isRequired,
        age: PropTypes.number
    }

执行代码时提示以上问题，查看后才发现有个地方写错了！！
