How to fix when adding any component to app.jsx, the context creation error that pops up?

Question

React

Good time, there was a problem when adding components to the access point, such an error immediately pops up, how to fix it?

_react.default.createContext is not a function

App.jsx

import React from 'react';
import { render } from 'react-dom';
import { Provider } from 'react-redux';
import { BrowserRouter } from 'react-router-dom';

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

import configureStore from './Data/store/configureStore';
import Main from "./Templates/Main/Main";

const store = configureStore();
render(
    <div>
        <Provider store={store}>
            <BrowserRouter>
                <Main/>
            </BrowserRouter>
        </Provider>
    </div>,
    document.getElementById('app-root')
);

webpack config

'use strict';

var path = require('path');
var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
  devtool: 'eval-source-map',
  entry: [
    'webpack-hot-middleware/client?reload=true',
    path.join(__dirname, 'src/app.jsx')
  ],
  resolve: {
    root: [
      path.resolve(__dirname, "src"),
    ],
    extensions: ['', '.js', '.jsx', '.css']
  },
  output: {
    path: path.join(__dirname, '/public/'),
    filename: '[name].js',
    publicPath: '/'
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: 'src/index.tpl.html',
      inject: 'body',
      filename: 'index.html'
    }),
    new webpack.optimize.OccurenceOrderPlugin(),
    new webpack.HotModuleReplacementPlugin(),
    new webpack.NoErrorsPlugin(),
    new webpack.DefinePlugin({
      'process.env.NODE_ENV': JSON.stringify('development')
    })
  ],
  module: {
    loaders: [{
      test: /\.jsx?$/,
      exclude: /node_modules/,
      loader: 'babel',
      query: {
        presets: ['es2015', 'react']
      }
    }, {
      test: /\.css$/,
      loader: 'style!css'
    }]
  }
};

Google advises switching to version 16 of react, but I don't think this is a problem with the old version.

Clear. You think again .

"react-redux": "^6.0.0"

Let's open the documentation and see that

React Redux 6.x requires React 16.4 or later .
