Javascript ReactJS+；Redux，获取错误“；失败的支柱类型'的右侧；instanceof'；“不可赎回”；

我正在帮助React开发一个web应用程序，我们正在使用Redux进行全局状态控制

我不明白的是，为什么我们会在浏览器控制台上看到这些警告？需要什么才能让它消失？在声明道具类型时似乎出现了问题，但我不知道如何正确执行

以下是警告和相关代码，为简洁起见进行了简化

SearchBar.jsx

import React from 'react';
import PropTypes from 'prop-types';
import { bindActionCreators } from 'redux';
import { connect } from 'react-redux';
import * as SearchBarActions from './redux/actions';

const SearchBar = props => {
  const handleSearch = () => {
    [some code here]
  };

  return (
    <div className="searchbar w-100 my-2">
      <div className="input-group">
        <input
          id="searchBar"
          name="searchBar"
          type="text"
          className="form-control rounded"
          aria-describedby="button-main-search"
        />
        <button
          type="button"
          className="btn btn-lg fas fa-search text-light pl-3"
          id="button-main-search"
          onClick={handleSearch}
        >
          <span className="sr-only">Search</span>
        </button>
      </div>
    </div>
  );
};

SearchBar.propTypes = {
  actions: PropTypes.instanceOf(SearchBarActions),
};

SearchBar.defaultProps = {};

export default connect(null, dispatch => ({
  actions: bindActionCreators(SearchBarActions, dispatch),
}))(SearchBar);

常数

import * as CONSTANTS from './constants';

export const addSearchLogs = searchLogs => {
  return {
    type: CONSTANTS.ADD_SEARCH_LOGS,
    searchLogs,
  };
};

export const clearSearchLogs = () => {
  return {
    type: CONSTANTS.CLEAR_SEARCH_LOGS,
  };
};

export const ADD_SEARCH_LOGS = 'ADD_SEARCH_LOGS';
export const CLEAR_SEARCH_LOGS = 'CLEAR_SEARCH_LOGS';

PropTypes.instanceOf

将prop定义为特定类的实例，通常是React组件，但肯定是函数

您的

SearchBarActions

变量是一个JavaScript对象，不可调用，尽管它的TitleCase名为

我想你想要更像这样的东西：

  actions: PropTypes.shape({
    addSearchLogs: PropTypes.func,
    clearSearchLogs: PropTypes.func
  }),

Aaron，你搞定了！非常感谢你的解释。使用您的答案，我还可以修复应用程序中显示相同警告的其他区域。很高兴为您提供帮助，Leandro！
