'Module not found: Error: Can't resolve 'react-dom/client'

I am using react with the following packages:

{
  "name": "demo",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^5.16.4",
    "@testing-library/react": "^13.0.1",
    "@testing-library/user-event": "^13.5.0",
    "h3-js": "^3.7.2",
    "leaflet": "^1.7.1",
    "react": "^17.0.1",
    "react-dom": "^17.0.1",
    "react-leaflet": "3.0.2",
    "react-scripts": "5.0.1",
    "web-vitals": "^2.1.4"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

My index.js looks like the following:

import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
import reportWebVitals from './reportWebVitals';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>
);

reportWebVitals();

My App.js is like the following:

import React from "react";
import { render } from "react-dom";
import LeafletMap from "./Map";

class App extends React.Component {
  state = { resolution: 8, kRing: 0 };

  constructor(props) {
    super(props);
    this.state = { resolution: 8, kRing: 0 };
  }

  render() {
    return (
      <div>
        <LeafletMap
          resolution={this.state.resolution}
          kRing={this.state.kRing}
        />
        Resolution:
        <input
          type="number"
          min={0}
          max={15}
          onChange={this.onChangeResolution}
          defaultValue={8}
        />
        <br />
        K Rings:
        <input
          type="number"
          min={0}
          max={100}
          onChange={this.onChangeKRings}
          defaultValue={0}
        />
      </div>
    );
  }

  onChangeResolution = (e) => {
    this.setState({ resolution: Number.parseInt(e.target.value) });
  };
  onChangeKRings = (e) => {
    this.setState({ kRing: Number.parseInt(e.target.value) });
  };
}

export default App;

When I run my app with npm run start I get the following error:

Compiled with problems:X

ERROR in ./src/index.js 5:0-40

Module not found: Error: Can't resolve 'react-dom/client' in '/home/Desktop/Code/demo_app/src'

I reinstalled all packages and its also listed in npm list:

Any suggestions why I have problems compiling my application?

The final solution that worked for me was simply to change the React 18 index.js file to the following:

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import reportWebVitals from './reportWebVitals';

ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);

// If you want to start measuring performance in your app, pass a function
// to log results (for example: reportWebVitals(console.log))
reportWebVitals();

You still have the older versions of "react" and "react-dom" in your dependencies. To solve it:

delete these two lines:

    "react": "^17.0.1",
    "react-dom": "^17.0.1",

Replace them with:

    "react": "^18.1.0",
    "react-dom": "^18.1.0",

delete the "node_modules" folder
do npm install This should solve your issue and update your app to react18

I had a similar problem and I solved it by adding

 "noImplicitAny": false

on the tsconfig.json

You might need to downgrade React and react-dom, here is index.js:

React 17 example:

import React from "react";
import { render } from "react-dom";
import "./index.css";
import App from "./App";

const root = document.getElementById("root");
render(<App />, root);

React 18 example:

import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>
);

For react version 18.1 (with typescript), this works for me

    import React from "react";
    import { createRoot } from "react-dom/client";
    import reportWebVitals from "./reportWebVitals";
    import App from "./App";
    const root = createRoot(
        document.getElementById("root") as HTMLElement
    );
    root.render(
       <React.StrictMode>
          <App />
       </React.StrictMode>
    );
    reportWebVitals();
