从React 15.5.0开始不推荐使用React.PropTypes [英] React.PropTypes is deprecated since React 15.5.0

问题描述

我正遇到一个问题，我试图导入一个静态组件并将其用于父组件中.我收到React未定义的错误.

I am facing an issue where I am trying to import a static component and use it in the parent component. I am getting React undefined error.

这是我所做的 父组件

import React from 'react';
import TableHeader from 'TableHeader';
import TableRow from 'TableRow';
import UTIL from '../../services/Utils';

export default class Table extends React.Component {

    render() {
        return (<div>
            <TableHeader labels={this.props.labels}/>
            <div className="table-body js-filtered-data-wrapper sortable">
                {this.renderTableRows()}
            </div>

        </div>
        )
    }
    renderTableRows() {
        return this.props.teamlist.map((listItem, i) => {
            return (
                <TableRow key={i}
                               data={listItem}
                               labels={this.props.labels}
                />
            )
        });
    }
}

在我的TableHeader文件中，代码是

in my TableHeader file the code is

import { PropTypes } from 'react';

const TableHeader = (props) => {
    let labels = props.labels;
    return (
        <ul className="table-header">
            <li className="table-row header ">
                <div className="player-name">{labels.playername}</div>
            </li>
        </ul>
    )
}

TableHeader.propTypes = {
    labels : PropTypes.object.isRequired
}

export default TableHeader;

我得到的错误是

Uncaught ReferenceError: React is not defined
    at TableHeader (webpack:///./src/components/pro-am/TableHeader.jsx?:13)

推荐答案

Imoprt React也位于TableHeader组件中:

Imoprt React in the TableHeader component too:

注意:在最新版本的React中，已移动PropTypes 到单独的程序包(prop-types).因此，从那里导入它就像

NOTE: With the latest version of React the PropTypes have been moved to a Separate package(prop-types). So import it from there like

import React,{ PropTypes } from 'react';

const TableHeader = (props) => {
    let labels = props.labels;
    return (
        <ul className="table-header">
            <li className="table-row header ">
                <div className="player-name">{labels.playername}</div>
            </li>
        </ul>
    )
}

TableHeader.propTypes = {
    labels : PropTypes.object.isRequired
}

export default TableHeader;

如果使用v15.5.0或更高版本，请使用单独软件包中的PropTypes

If using v15.5.0 or above use PropTypes from a separate package

import React from 'react';
import PropTypes from 'prop-types';

const TableHeader = (props) => {
    let labels = props.labels;
    return (
        <ul className="table-header">
            <li className="table-row header ">
                <div className="player-name">{labels.playername}</div>
            </li>
        </ul>
    )
}

TableHeader.propTypes = {
    labels : PropTypes.object.isRequired
}

export default TableHeader;
