警告:道具类型失败:游戏:道具类型“游戏”无效;它必须是一个函数,通常来自 React.PropTypes

Warning: Failed prop type: Game: prop type `game` is invalid; it must be a function, usually from React.PropTypes

import React, { PropTypes } from 'react';
import { connect } from 'react-redux';
import { bindActionCreators } from 'redux';

// import UI components
import GameList from '../components/game/GameList';

// import actions
import gameActions from '../actions/game';

const Game = (props) => {
  const { game, actions } = props;
  return (
    <GameList game={game} actions={actions} />
  );
};

Game.propTypes = {
  game: PropTypes.shape.isRequired,
  actions: PropTypes.shape.isRequired,
};

function mapStateToProps(state) {
  return {
    game: state.game,
  };
}

function mapDispatchToProps(dispatch) {
  return {
    actions: bindActionCreators(gameActions, dispatch),
  };
}

export default connect(mapStateToProps, mapDispatchToProps)(Game);

我试图将这两个道具作为对象传递给一个组件,但我收到无效的道具类型错误。

我需要这两个 props 是对象,我很确定它们是对象,为什么需要它们是函数?

问题在于您的 propTypes 定义:

Game.propTypes = {
  game: PropTypes.shape.isRequired,
  actions: PropTypes.shape.isRequired,
};

对于每个你应该做的事情:PropTypes.shape({}).isRequiredPropTypes.object.isRequired

通过 shape 它传递形状函数作为期望。
