Ran ">npm install react-bootstrap bootstrap"

Imported the Button Component from Bootstrap and added to the page. I am getting the below error.

My package.json has below entries for bootstrap along with other entries for react.

```
"react-bootstrap": "^1.0.0-beta.14",
"bootstrap": "^4.3.1",

import React, { Component } from 'react';
import ToggleButtonGroup from 'react-bootstrap/ToggleButtonGroup';
import ToggleButton from 'react-bootstrap/ToggleButton';

class MyButtonComponent extends Component {

    render() {
        let value  =1;
        return (

           <ToggleButtonGroup type="checkbox" value={value} >
             <ToggleButton value={1}>Option 1</ToggleButton>
             <ToggleButton value={2}>Option 2</ToggleButton>
             <ToggleButton value={3}>Option 3</ToggleButton>
           </ToggleButtonGroup>

        );
    }
}

export default MyButtonComponent ;

```
