SyntaxError: Unexpected token 'export' on '#react-navigation' - javascript

I created a new React Native project and used Jest testing, it goes very well. But when I try it in an existing app it couldn't work, instead it gave me the following error.I suspect it is a configuration error that caused this problem:
Error
SyntaxError: Unexpected token 'export'

I had tried many accepted answers on StackOverflow and internet but no luck on solving this problem.These are some of the links I can remember of, there might be a little unrelated because I faced the same problem with other modules apart from #react-navigation:

Getting "TypeError: (0 , _firestore.getFirestore) is not a function" When trying to perform integration testing with Jest, Firebase and Expo

I am getting the error "TypeError: (0 , _firestore.getFirestore) is not a function" When trying to run a Jest integration test with my app's Login page. It seems that Jest is unable to recognise it as a function despite the rest of my Expo app being able to recognise it just fine.
I am wondering if this is because My firebase config file uses Web Version 9 as required by Expo and if there are any solutions or alternatives to this.
Thanks
import { initializeApp } from 'firebase/app';
import { getFirestore } from "firebase/firestore";
// Firebase API
const firebaseConfig = {
};
const app = initializeApp(firebaseConfig);
export const db = getFirestore(app);
I have tried import { firestore } from "firebase/firestore", import "firebase/firestore",
export const db+ app.firestore().
None of them works.

Somebody know what is wrong? I can't figure it out. Maybe react-router-dom need other version of some other package?
Thanks in advance
react-router-dom#6 is completely written in typescript, so you can remove "#types/react-router": "^5.1.14" and "#types/react-router-dom": "^5.3.3" from the project's dependencies as they are no longer necessary and may possibly mess with any linters and transpilers your project uses.
npm uninstall -S #types/react-router #types/react-router-dom
You've also a conflicting version of react-router installed and it should be removed. react-router-dom re-exports all of react-router for convenience.
npm uninstall -S react-router
The only other issue I see is in the code. The react-router-dom#6 Route component API changed significantly from v5; there is no longer any component, and render and children function props, all replaced by a single element prop taking a ReactNode value, a.k.a. JSX.
Example:
<BrowserRouter>
<Routes>
<Route
path="/"
key="homepage"
element={<MyComponent />}
/>
</Routes>
</BrowserRouter>
Unfortunately same problem after update my code and uninstall react-router library.
After 4 hours of debugging I find out problem is in import of files.
When I import file by this way:
index.tsx
import {profileAction} from './model';
// import {profileAction} from './model/action'; // when I change import to this it works
and model/index.tsx looks
export * from './action';
export * from './action-type';
export * from './api';
export * from './state';
export * from './sagas';
and model/action.ts looks:
export const profileAction = {...}
then I ever get error like this:
index.tsx:66 Uncaught TypeError: Object(...) is not a function
at Module.<anonymous> (index.tsx:66:1)
at ./src/app/profile/component/profile-gallery-filter-form/index.tsx (index.tsx:94:1)
at __webpack_require__ (bootstrap:856:1)
at fn (bootstrap:150:1)
i haven't a clue why my imports are broken. Since update react-router-dom all imports works fine.

Uncaught TypeError: Object(…) is not a function in internal Vue3

I have strange error, i don’t know what causing this but last time i develop my project was fine. After no reason my chrome browser lost its cache data (next day). when i run my vue3 project the error appears. What console logs said

Somebody please help me
I also encountered the same problem, and finally found that when I imported nanoid, deconstruction was not used. After adding {}, the error was resolved. You can see if it is the problem of importing third-party libraries.

Any idea?

Trying to unit test a React component using Jest and Enzyme

I am trying to run a simple jest and enzyme test against a react component and test throws: ReferenceError: React is not defined. I followed all simple tutorials on jest and react testing but all of them resulted in the same exception. I used npm test and result was the same as yarn test, React not defined. I am confused. Any help would be appreciated.
Checkbox.test.jsx: simple test
import { shallow } from 'enzyme';
import sinon from 'sinon';
import Checkbox from './Checkbox';
describe('<Checkbox />', () => {
it('should render three <Checkbox /> components', () => {
const wrapper = shallow(<Checkbox />);
expect(wrapper.prop('title')).toEqual('Events — Event Radar');
});
});
Console log
$ yarn test
FAIL src\components\ReusableComponents\Checkbox.test.jsx (5.248s)
<Checkbox />

Import React in your test and the error should disappear:
import React from 'react';
I tried removing this import in one of my tests and I got the same error you mentioned.
I hope this helps.
