Rendering react-bootstrap component causing errors - reactjs

Question

I am trying to add the react-bootstrap accordion to my react website. However, when I add it all I see is a white screen on the page that contains the accordion. I've installed react-bootstrap and bootstrap with npm. After refreshing the page I get the error:
Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.
import React, {Component} from 'react';
import Accordion from 'react-bootstrap/Accordion'
class Collapsible extends Component{
render() {
return(
<section className="container">
<Accordion>
<Accordion.Item eventKey="0">
<Accordion.Header>Accordion Item #1</Accordion.Header>
<Accordion.Body>

}
}
export default Collapsible;

You seem to be using version 4.x (1.6.x) of react-bootstrap, but the components you are using are in version 5.x (2.x) of react-bootstrap.
Version 4 Accordion
Has Accordion, Accordion.Toggle, and Accordion.Collapse components.
<Accordion defaultActiveKey="0">

<Card.Header>
<Accordion.Toggle as={Button} variant="link" eventKey="0">

</Accordion.Toggle>
</Card.Header>
<Accordion.Collapse eventKey="0">
<Card.Body>Hello! I'm the body</Card.Body>
</Accordion.Collapse>
</Card>
<Card>
<Card.Header>
<Accordion.Toggle as={Button} variant="link" eventKey="1">
Click me!
</Accordion.Toggle>
