无法处理未捕获的类型错误：无法读取 createRouterReducer 处未定义的属性“位置”

我在将路由器连接到 rootReducer 时遇到问题，控制台日志

未捕获的类型错误：无法读取未定义的属性“位置” 在 createRouterReducer (reducer.js?005c:9) ...

不知道如何修复它并将路由器连接到减速器。

app.jsx


import React from 'react';
import { render } from 'react-dom';
import App from './containers/app'
import {Provider} from 'react-redux'
import {ConnectedRouter} from 'connected-react-router'
import store, {history} from './store'

import './react-select/dist/react-select.css';

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

store.js


import { createStore, applyMiddleware, compose } from 'redux'
import { connectRouter, routerMiddleware } from 'connected-react-router'
import thunk from 'redux-thunk'
import rootReducer from './reducers/rootReducer'


var createHistory = require("history").createBrowserHistory
export const history = createHistory()

const initialState = {}
const enhancers = []
const middleware = [
    thunk,
    routerMiddleware(history)
]
.....
const store = createStore(
    connectRouter(history)(rootReducer),
    initialState,
    composedEnhancers
)

export default store

减速器/rootReducer.js

import {combineReducers} from 'redux'
import invoices from './invoices'
import customers from './customers'
import products from './products'
import {connectRouter} from 'connected-react-router'
import {history} from '../store'

const rootReducer = combineReducers({
        invoices: invoices,
        customers: customers,
        products: products,
        router: connectRouter(history)
    }
);

export default rootReducer;

期望将路由器连接到rootReducer，但出现错误

历史记录需要移至单独的文件中。 您正在 store.js 中创建历史记录，而 store.js 需要 reducer.js，而 rootReducer.js 需要历史记录。所以router: connectRouter(history)rootReducer.js 中不会有正确的值

这是一个基于您的代码的工作示例:
