Reactjs 盖茨比，雷多克斯，找不到；商店「；在「；连接（CartContainer）"；

代码在react redux v5中运行良好，但当我升级到v7时，在使用CartContainer导航到页面时，我遇到了以下运行时错误：

react-dom.development.js:11102 Uncaught Error: Could not find "store" in the context of 
"Connect(CartContainer)". Either wrap the root component in a <Provider>, or pass a custom 
React context provider to <Provider> and the corresponding React context consumer 
to Connect(CartContainer) in connect options.

讨论中的连接组件CartContainer.js如下所示：

import React from 'react'
import PropTypes from 'prop-types'
import { connect } from 'react-redux'
import { checkout } from '../actions'
import { getTotal, getCartProducts } from '../reducers'
import Cart from '../components/checkout/Cart'

const CartContainer = ({ products, total, checkout }) => (
  <Cart
    products={products}
    total={total}
    onCheckoutClicked={() => checkout(products)} />
)

CartContainer.propTypes = {
  products: PropTypes.arrayOf(PropTypes.shape({
    id: PropTypes.number.isRequired,
    title: PropTypes.string.isRequired,
    price: PropTypes.number.isRequired,
    quantity: PropTypes.number.isRequired
  })).isRequired,
  total: PropTypes.string,
  checkout: PropTypes.func.isRequired
}

const mapStateToProps = (state) => ({
  products: getCartProducts(state),
  total: getTotal(state)
})

export default connect(
  mapStateToProps,
  { checkout }
)(CartContainer)

您可以从“/ReduxWrapper”像导出{defaultaswraprootement}一样导出wraprootement但是你的文件名不应该是你文章中提到的盖茨比说唱歌手吗。因此，解决方案应该是从“/GatsbyWrapper”导出{defaultaswraprootement}@Shubham Khatri刚刚更改了文件名，所以这个程序已经有了ReduxWrapper.js，所以对程序没有任何更改但是你的文件名不应该是你文章中提到的盖茨比说唱歌手吗。因此，解决方案应该是从“/GatsbyWrapper”导出{defaultaswraprootement}@Shubham Khatri刚刚更改了文件名，程序已经有ReduxWrapper.js，所以程序没有更改。

export { default as wrapRootElement } from './ReduxWrapper';

import React from 'react'
import PropTypes from 'prop-types'
import { connect } from 'react-redux'
import { checkout } from '../actions'
import { getTotal, getCartProducts } from '../reducers'
import Cart from '../components/checkout/Cart'

const CartContainer = ({ products, total, checkout }) => (
  <Cart
    products={products}
    total={total}
    onCheckoutClicked={() => checkout(products)} />
)

CartContainer.propTypes = {
  products: PropTypes.arrayOf(PropTypes.shape({
    id: PropTypes.number.isRequired,
    title: PropTypes.string.isRequired,
    price: PropTypes.number.isRequired,
    quantity: PropTypes.number.isRequired
  })).isRequired,
  total: PropTypes.string,
  checkout: PropTypes.func.isRequired
}

const mapStateToProps = (state) => ({
  products: getCartProducts(state),
  total: getTotal(state)
})

export default connect(
  mapStateToProps,
  { checkout }
)(CartContainer)
