PropTypes React Native不是对象 [英] PropTypes React Native is not an object

问题描述

我在响应本机代码时遇到PropTypes问题:

I have a problem with PropTypes in react native my code :

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

export default class Star extends Component {
    render() {
        return ( <Text> Hello </Text> );
    }
}

Star.propTypes = {
    fullStar: PropTypes.string.isRequired,
    halfStar: PropTypes.string.isRequired,
    emptyStar: PropTypes.string.isRequired,
    half: PropTypes.bool,
    count: PropTypes.number,
    size: PropTypes.number,
}

Star.defaultProps = {
    fullStar: "",
    halfStar: "",
    emtyStar: "",
    half: 'true',
    count: 5,
    size: 30,
}

我的错误未定义不是对象(正在评估'_react2.PropTypes.string')

My error is undefined is not an object (evaluating '_react2.PropTypes.string')

推荐答案

PropTypes移到了单独的程序包中.使用prop-types程序包.

PropTypes moved into separate package. Use prop-types package.

更多信息此处.

注意:

React.PropTypes已经移到了另一个包中 v15.5.请改用 prop-types库.我们提供 codemod脚本来自动执行转换.

React.PropTypes has moved into a different package since React v15.5. Please use the prop-types library instead. We provide a codemod script to automate the conversion.
