React-bootstrap components breake my whole page-CodePudding

I'm developing a React frontend with react-bootstrap. React is working fine, but when I use any react-bootstrap component in any page, Chrome just shows a fully blank page.

I think the problem might be in the index.html. I have this in the <head> tag, but no alert showing, I'm not sure if it should.

<script src="https://unpkg.com/react/umd/react.production.min.js"></script>
<script src="https://unpkg.com/react-dom/umd/react-dom.production.min.js"></script>
<script src="https://unpkg.com/react-bootstrap@next/dist/react-bootstrap.min.js"></script>

<script>var Alert = ReactBootstrap.Alert;</script>

Anyway, here's all the other code I consider relevant:

This is my index.js:

import React from 'react';
import {createRoot} from 'react-dom/client';
import { BrowserRouter } from 'react-router-dom';
import 'bootstrap/dist/css/bootstrap.min.css';
import './index.scss';
import App from './App';
import reportWebVitals from './reportWebVitals';

const rootElement = document.getElementById('root');
const root = createRoot(rootElement);

root.render(
    <React.StrictMode>
        <BrowserRouter>
            <App />
        </BrowserRouter>
    </React.StrictMode>
);

reportWebVitals();

This is my App.js working fine, Chrome shows the text:

import React from 'react';

export default function App() {
    return (
        <div className="App">
            <p>This is some text.</p>
        </div>
    );
}

This is my App.js not working. It doesn't give any error, just a completely blank page, not even the text shows.

import React from 'react';
import { Button } from 'react-bootstrap';

export default function App() {
    return (
        <div className="App">
            <p>This is some text.</p>
            <Button variant="primary" type="button" value="Input" />
        </div>
    );
}

This happens with any bootstrap component, not only the Button (I've tried a few). I'm new to React, so any kind of help is welcome.

EDIT: Here's a screenshot of the Chrome console when the blank page problem happens.

It seems like you have set up your react-bootstrap & bootstrap not properly. When using react-bootstrap, you don't need the js-bundle from bootstrap, but the css. You have two options:

Install bootstrap (npm i bootstrap) and add import 'bootstrap/dist/css/bootstrap.min.css'; to your index.js or App.js file

Or use CDN: Paste following snippet into your index.html:

<link
  rel="stylesheet"
  href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css"
  integrity="sha384-1BmE4kWBq78iYhFldvKuhfTAU6auU8tT94WrHftjDbrCEXSU1oBoqyl2QvZ6jIW3"
  crossorigin="anonymous"

I solved it. I needed to actually install all the packages with npm in my project folder. I had them installed in my Windows user folder and globally, but not in my project.

Basically, just open a cmd in your project folder and run:

C:\SomePath\MyReactProject>npm install react-bootstrap bootstrap

Try this

<Button href="#" variant="primary" type="button" value="Input" />
