javascript - 通过主 React 包访问 PropTypes 已被弃用

Question

我正在使用 redux，但是当我运行我的代码时出现这个错误:

Accessing PropTypes via the main React package is deprecated. Use the prop-types package from npm instead.

我安装

npm i prop-types -S

但是我还是有同样的错误。

./components/action/article.js

import * as ArticleActionTypes   from '../actiontypes/article';

export const AddArticle = (name, description, prix, image) => {
    return {
        type: ArticleActionTypes.ADD_ARTICLE,
        name, 
        description, 
        prix,
        image
    }
}

export const RemoveArticle = index => {
    return {
        type: ArticleActionTypes.REMOVE_ARTICLE,
        index
    }
}

./components/actiontypes/article.js

export const ADD_ARTICLE = 'article/ADD_ARTICLE';
export const REMOVE_ARTICLE = 'article/REMOVE_ARTICLE';
export const UPDATE_ARTICLE = 'article/UPDATE_ARTICLE';

./components/reducers/article.js

import * as ArticleActionTypes   from '../actiontypes/article';

const initialState = [
    {
        name: 'test',
        description: 'test',
        prix: 'test',
        image: 'url'
    },
    {
        name: 'test',
        description: 'test',
        prix: test,
        image: 'url'
    }
]

export default function Article (state=initialState, action){
    switch(action.type){
        case ArticleActionTypes.ADD_ARTICLE : 
            return [
                ...state,
                {
                    name: action.name,
                    description: action.description,
                    prix: action.prix,
                    image: action.image
                }
            ];
        case ArticleActionTypes.REMOVE_ARTICLE :
            return [
                ...state.slice(0, action.index),
                ...state.slice(action.index +1)
            ] ;
        default: return state;
    }
}

索引.js

import React            from 'react';
import { render }       from 'react-dom';
import {Provider}       from 'react-redux';
import {createStore}    from 'redux';

import ArticleReducer   from './components/reducers/article';
import Scoreboard       from './components/containers/Scoreboard';

const store = createStore(
    ArticleReducer,
    window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__()
)

render(<Provider>
            <Scoreboard store={store}/>
        </Provider>, document.getElementById('root'));

./components/containers/Scorboard.js

import React                            from 'react';
import {connect}                        from 'react-redux';
import {bindActionCreactors}            from 'redux';
import PropTypes                        from 'prop-types';

class Scoreboard extends React.Component {

    render(){
        return (
            <div>
              Scoreboard
            </div>
        )
    }
}

const mapStateToProps = state => {
    {
        articles :state 
    }
}

Scoreboard.propTypes = {
  articles: PropTypes.array.isRequired
}

export default connect(mapStateToProps)(Scoreboard);

正如其他人所提到的 - 如果您已经针对 PropTypes 使用审核了自己的项目，但您仍然看到警告 - 它可能来自上游依赖项。追踪此警告原因的一种方法是在记录它的位置设置调试断点，然后返回到调用方。这是我制作的一个简单的录音示例:

(提供更高质量的版本 here 。)

一旦您确定了有问题的库，请考虑提交一个 Github 问题(或者更好的是 - 一个 PR!)以通知作者新警告。

与此同时，这只是一个开发模式警告，因此它不会影响应用程序的生产使用。
