不推荐通过主React包访​​问PropTypes

Question

我正在使用redux但是当我运行我的代码时出现此错误:

不推荐通过主React包访​​问PropTypes.请改用npm中的prop-types包.

我安装

npm i prop-types -S

但我仍然有同样的错误.

./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;
    }
}

index.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);

Answer 1

正如其他人所提到的 - 如果您已经审核了自己的项目以供PropTypes使用,但您仍然看到了警告 - 它可能来自上游依赖项.您可以通过设置调试断点来记录此警告的一种方法,然后逐步返回调用者.这是我制作的快速录制示例:

(此处提供更高质量的版本.)

一旦您确定了相关库,请考虑提交Github问题(或者更好的PR - !)以通知作者新警告.

同时,这只是一个开发模式警告,所以它不应该影响应用程序的生产使用.

Answer 2

由于React v15.5.0 React.PropTypes的发布已弃用并已移至另一个库.您应该使用npm install prop-types并使用PropTypes.

./components/containers/Scorboard.js中的代码看起来非常好,您可能React.PropTypes在代码中的其他位置.

另一个选择是你正在使用的某些依赖仍然是旧的方式.您可以尝试更新您的依赖项,但由于此弃用很新,我怀疑每个库都已发布更新.

UPDATE

似乎redux已经更新了它的依赖关系以使用React v15.5.0并且摆脱了弃用警告.它也在v4和v5中修复.

我这样解决了这个警告:

已安装的PropTypes

# npm install -S prop-types

像这样导入PropTypes

import PropTypes from 'prop-types';

而不是这样做:

import { PropTypes } from 'react';
