React-Redux：在“ ConnectUploadInternal”的上下文中找不到“存储”

问题描述

重复的代码沙箱 https://ndg6d.csb.app/

完全错误 Uncaught Error: Could not find "store" in the context of "Connect(UploadInternal)". 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(UploadInternal) in connect opt。

情况 一切工作正常，然后将react 15.x更新到16.13.x，react-redux从5.x更新到7.2.x，现在上面的错误发生在几个级别的组件上。

我已经检查了ReactRedux Docs，并确认我已按照他们的建议步骤进行操作。我已经阅读了StackOverflow此处列出的所有其他类似案例，但尚未解决问题。具体来说，将商店传递给包装了根应用<Provider store={store}><App/></Provider>的提供程序，并且中间组件通过ReactRedux与connect连接，因此我不确定为什么其中一个嵌套子级没有有权访问商店。

index.js

   const store = configureStore(preloadedState);

    ReactDOM.render((
        <Provider store={store}>
          <MuiThemeProvider muiTheme={getMuiTheme()}>
            <ConnectedRouter history={history}>
              <Route component={App} />
            </ConnectedRouter>
          </MuiThemeProvider>
        </Provider>
      ),document.getElementById('root')
    );

configureStore.js

import {createStore,combineReducers,applyMiddleware,compose} from 'redux';
import rootReducer from '../components/app/reducers';
import thunk from 'redux-thunk';
import { connectRouter,routerMiddleware } from 'connected-react-router'
import createHistory from 'history/createBrowserHistory'
import history from '../history/history'

export default function configureStore(initialState) {

  var middleware;
  var storeEnhancer;
  var store;

  if(initialState){
    middleware = [thunk,routerMiddleware(history)];

    storeEnhancer = compose(
      applyMiddleware(...middleware)
    );

    store =   createStore(
      combineReducers({
        root: rootReducer,router: connectRouter(history) 
      }),initialState,applyMiddleware(...middleware)););
  }else{
    middleware = [thunk];
    storeEnhancer = compose(
      applyMiddleware(...middleware)
    );

    store = createStore(
      combineReducers({
        root: rootReducer,applyMiddleware(...middleware)););
  }


    if (module.hot) {
        // Enable Webpack hot module replacement for reducers
        module.hot.accept('../reducers',() => {
            const nextRootReducer = require('../reducers');
            store.replaceReducer(nextRootReducer);
        });
    }

    return store;
}

Child.jsx和NestedChild.jsx（Inside Child.jsx）-仅在文件底部显示组件已连接：

const mapStateToProps = (state,ownProps) => {

  const {root,...rest} = state;
  const reduxState = {...root};

  return {
    reduxState
  };
};


const mapDispatchToProps = (dispatch)=>{
  return {dispatch};
};

const mergeProps = (stateProps,dispatchProps,ownProps) => {
  return Object.assign({},ownProps,stateProps,dispatchProps);
};

const options = {

};


Child_or_NestedChild = connect(mapStateToProps,mapDispatchToProps,mergeProps,options)(Child_or_NestedChild);

export default muiThemeable()(Child_or_NestedChild);
