Javascript React Redux存储设置：错误：找不到；商店「；

我正在尝试在此处设置react redux存储，浏览器中显示错误消息：

错误：在“连接（卡）”上下文中找不到“存储”。将根组件包装在中，或者在Connect options中将自定义的React上下文提供程序传递给和相应的React上下文使用者进行连接（卡片）。

Index.js

import React from 'react';
import ReactDOM from 'react-dom';
import {createStore} from "redux";
import reducer from "./Store/reducer";
import {Provider} from "react-redux";

const store = createStore(reducer);

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

reducer.js

import {combineReducers} from "redux";

const initialState = {
  counter: 0
};

const reducer = (state = initialState, action) => {
  return state;
};

export default reducer

这是一个非常简单的设置，我不确定哪里出了问题，请帮助。

只需从react redux导入connect：

import { connect } from 'react-redux'

还有，为什么你们要在柜台组件中使用卡片组件呢。您为什么不直接使用卡组件连接到那里？

此导入有效。。我的问题是从IDE自动导入。。谢谢

import {combineReducers} from "redux";

const initialState = {
  counter: 0
};

const reducer = (state = initialState, action) => {
  return state;
};

export default reducer

import { connect } from 'react-redux'
