React + Redux示例。对象作为React子对象无效

Question

我无法让简单的React和Redux示例正常工作，需要一些帮助。我尝试分派incrementNumber操作时，我收到以下错误。我将在下面粘贴我的代码。 Or you can use the Github link here.提前致谢！

index.js（App root）

import React from 'react';
import { render } from 'react-dom';
import { Provider } from 'react-redux';
import store from './store/configureStore';

import App from './containers/App';

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

configureStore.js

import { createStore } from 'redux';
import rootReducer from '../reducers';

export default createStore(rootReducer);

index.js（root reducer）

import { combineReducers } from 'redux';
import numbersReducer from './numbersReducer';

const rootReducer = combineReducers({
    number: numbersReducer
});

export default rootReducer;

numbersReducer.js

import initialState from './initialState';

export default function numbersReducer(state = initialState.number, action) {
    switch (action.type) {
        case "INCREMENT_NUMBER":
            return { ...state, number: state.number + 1 }
        default:
            return state;
    }
}

initialState.js

export default {
    number: 0
}

App.js

import React from 'react';
import { connect } from 'react-redux';
import { incrementNumber } from '../actions/appActions';

export class App extends React.Component {

    componentDidMount() {
        this.props.dispatch(incrementNumber(1));
    }

    render() {
        return (
            <div>
                Current number: {this.props.number}
            </div>
        );
    }
}

const mapStateToProps = state => ({
    number: state.number
});

export default connect(mapStateToProps)(App);

appActions.js

export function incrementNumber(number) {
    return { type: "INCREMENT_NUMBER", number}
}

Answer 1

<div>
         Current number: {this.props.number.number}
</div>

并且也改变了这一点。

export default function numbersReducer(state = initialState, action) {
    switch (action.type) {
        case "INCREMENT_NUMBER": {

            return { ...state, number: state.number + 1 }
        }
        default:
            return state;
    }
}

/ * state = initialState * /

Answer 2

const rootReducer = combineReducers({
    number: numbersReducer
});

在combineReducers参数对象中，"number"不能为属性。因为numbersReducer在其"number"中已经具有此属性initialState。
