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')
);

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