When attempting to import a component from react-bootstrap, an error is thrown

Every time I try to use a component from 'react-bootstrap', I encounter a strange error. Here is a small example where I am importing the "HelpBlock" component.

import PropTypes from 'prop-types';
import React from 'react';
import HelpBlock from 'react-bootstrap';

class RegisterFormDetails extends React.Component {

...
              <HelpBlock>{validationErrorMessage}</HelpBlock>
            }
          </div>
        </div>
    );
      };
export default RegisterFormDetails;

However, I keep getting this error:

Attempted import error: 'react-bootstrap' does not contain a default export (imported as 'HelpBlock').

Here is my package.json file:

    {
  "name": "my-app",
  "version": "0.1.0",
  "private": true,
  "dependencies": {},
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ],
  "devDependencies": {
    "bootstrap": "^4.3.1",
    "lodash": "^4.17.11",
    "prop-types": "^15.7.2",
    "react": "^16.8.3",
    "react-bootstrap": "^0.32.1",
    "react-bootstrap-sweetalert": "^4.4.1",
    "react-dom": "^16.8.3",
    "react-scripts": "^2.1.5",
    "react-select": "^2.4.1"
  }
}

Can someone please help me with this issue? I have confirmed that the react-bootstrap folder in node_modules contains the component I'm trying to import.

If you want to use specific components from a library, you can import them individually like this:

import HelpBlock from 'react-bootstrap/HelpBlock';

The first method shown above is importing the component directly. This is considered a default import, which means you are exporting with export default ..... It's important to note that there can only be one default export in a module. Since 'react-bootstrap' does not have a default export, you need to import the component directly.

Alternatively, you can import specific components by using curly braces like this:

import { HelpBlock } from 'react-bootstrap';

In this case, only the HelpBlock component will be imported into your project. I hope this explanation helps clarify things for you!
