Redux TypeError: Cannot read property 'apply' of undefined

I have disabled react devtools and redux devtools.

I've been searching for ways to deal with this problem for hours, and most of the problems are in compose while I don't change code at all.

import { createStore, applyMiddleware,compose } from 'redux';
import thunk from 'redux-thunk';
import rootReducer from './reducers';

const initialState={};

const middleware = [thunk];

const store = createStore(rootReducer,initialState,
    compose(
        applyMiddleware(...middleware),
        window.__REDUX_DEVTOOLS_EXTENSION__&& window.__REDUX_DEVTOOLS_EXTENSION__()
        )   
    );


export default store;

I really don't understand why this happened. I don't change anything and the last thing I do is just do git push origin master to my repository and suddenly when I compiled I got this error:

Iam Using this in my front end :

Solution

  • Update your redux dev tools from 2.16.0 to 2.16.1

    OR

    Remove this line from your code 

    window.__REDUX_DEVTOOLS_EXTENSION__&& window.__REDUX_DEVTOOLS_EXTENSION__()
