React Router: TypeError Cannot read properties of undefined (reading 'originalPositionFor')

Viewed 4187

Hi I am a beginner getting started with React Router, and generated the basic sources with create-react-app.

When I tried to setup the router according to the tutorial I get a TypeError. I attempted to reduce any excess code that may cause the problem until I ended up with just this

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import { Router } from 'react-router';

ReactDOM.render(
  <Router>
  </Router>,
  document.getElementById('root')
);

Yet I am still getting the same error

    ERROR in ./node_modules/history/index.js
    Module build failed (from ./node_modules/babel-loader/lib/index.js):

    webpack 5.68.0 compiled with 1 error in 2579 ms

Using version 6.2.1

    "react": "^17.0.2",
    "react-dom": "^17.0.2",
    "react-router": "^6.2.1",
    "react-router-dom": "^6.2.1",
    "react-scripts": "5.0.0"

I am completely baffled, any help is appreciated.

Edit

I think I found the problem. It appears that babel/core@7.17.0 had a breaking change that caused this issue (https://github.com/aws-amplify/amplify-ui/issues/1242). I used the solution from this comment https://github.com/aws-amplify/amplify-ui/issues/1242#issuecomment-1028471472, set my dependency to babel/core@17.16.12 and the error went away

There was an issue inside of @jridgewell/trace-mapping package.

The issue is already fixed and new version v0.2.3 was published.

If you are using npm7+ all you need to do is run npm update and you should be fine.

It seems like somebody made a mistake in the last version of react router dom. It's a bug that you can fix typing this in the console:

npm i -D @babel/core@7.16.12

Then follow any example in the documentation and you should be fine.

Go to ./node_modules/history/index.js

You will see something like this:

//# sourceMappingURL=index.js.map

Just uncomment out the last line

sourceMappingURL=index.js.map

I fixed this problem with 2 comments

npm uninstall react-router-dom

npm i react-router-dom@5.2.0

On the bash :

  1. npm uninstall react-router-dom

  2. npm i react-router-dom@6.0.2

My file package.json :

"react-router-dom": "^6.0.2"

My file app.js :

import { BrowserRouter as Router, Routes, Route } from "react-router-dom"
import Home from "./pages/Home";


function App() {
  return (
    <Router>
      <Routes>
        <Route path="/" element={<Home/>}  />
      </Routes>
    </Router>
  );
}

export default App;

it works for me !
