_react.default.createContext is not a function when using react-redux

I have a problem when adding components to the entry point, this error immediately pops up here, how to fix it? I also try add only Main component but anyway i take that error, in main.jsx just class with render method return "hello world"

_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'
    }]
  }
};

and dependencies

    "react": "^15.6.2",
    "react-addons-update": "^15.6.2",
    "react-bootstrap": "^1.0.0-beta.5",
    "react-dom": "^15.6.2",
    "react-helmet": "^5.2.0",
    "react-redux": "^6.0.0",
    "react-router": "^4.3.1",
    "react-router-dom": "^4.3.1",
    "react-select": "^1.0.0-beta13",
    "redux": "^4.0.1",
    "redux-thunk": "^2.3.0",
    "sequelize": "^3.20.0",
    "sqlite3": "^4.0.6"

Google advises to upgrade to version 16 of the ract, but I do not think that this is the problem of the old version.

Error: (0 , react__WEBPACK_IMPORTED_MODULE_1__.createContext) is not a function

Solution: At the beginning of the file type "use client" for the client-side environment-related files (When the component interacts with client-side)

Would happen if you use framer motion or some client hooks too. Just add use client; and thats it

I got the same issue but updating react and react-dom didn't help. I was using NextJS 13 with react-hook-form and the problem was that I forgot to put "use client" on the top of the page. This error occurred because you can't use hooks in server components.

ex:

"use client"; // top to the file

Extra info: Next.js Error: Hooks are not Allowed in Server Components

Upgrading react-dom package worked for me - try either of these (depending on your package manager)

  • npm update react react-dom

OR

  • yarn upgrade react react-dom

Got the issue fixed by updating the react and react-dom

npm update react react-dom

And ofcourse closing the server and restarting by npm start again.

Whenever you git pull or use someone's else code, try updating your package to the latest version using:

npm update

always check the React/React-dom versions, especially when you have imported project while following any online course !!

Also, if you don't want to update all packages by npm update just do :

npm i react@latest react-dom@latest

I Hope this helps !!

react-redux v6.0.0 uses the new context api provided by React and in order for it work, either you need to downgrade react-redux to v5.x.x or upgrade react and react-dom to v16.4 or above

If you are using yarn, you can run

yarn upgrade react react-dom

else with npm you can run

npm update react react-dom

You could also change the versions manually in package.json and run yarn install or npm install
