Attempted import error: 'react-bootstrap' does not contain a default export

React Bootstrap 2.0.2 is just impossible for me use because nothing can be imported. Every scrap of documentation and examples (even from the react-bootstrap folks themselves) seems to be for version 1.x. In fact, react-bootstrap's own https://github.com/react-bootstrap/code-sandbox-examples don't work when updated to use "2.0.x". I did open an issue in github, but there are people all over the web who seem to have working 2.0.x code, so I'm hoping someone knows the magic.

Please note: This question is for "react-bootstrap": "^2.0.2". Please don't point me to any questions regarding react-boostrap version 1.x. They do not apply and will be totally unhelpful.

Here's a rundown of code and the compile errors they produce.

Code + error pair #1

import foo from 'react-bootstrapt' produces Attempted import error: 'react-bootstrap' does not contain a default export

Code + error pair #2

import Jumbotron from 'react-bootstrap/Jumbotron'; produces Module not found: Can't resolve 'react-bootstrap/Jumbotron' in '/home/greg/my-react-bootstrap-2-app/src'

Code + error pair #3

import { Jumbotron, Container, Button, Alert } from 'react-bootstrap'; produces Attempted import error: 'Jumbotron' is not exported from 'react-bootstrap'.

Thanks for any help you can provide!
