bs_stepper_1.default is not a constructor

Hello, first of all thank you for your work on this.

Sorry if I join the conversation late but I just faced the same issue and managed to solve it somehow.

Just to throw on the table more details:

• angular version: 4.4.6
• typescript version: 2.3.4
• same code as in the example you gave

My thought on this is that it has something to do with esModuleInterop compiler option. Here is my (dirty but working) solution:

1. added esModuleInterop": true to compilerOptions in tsconfig.json
2. instead of

import Stepper from "bs-stepper";

I used

declare function require(name:string);
const Stepper = require('bs-stepper');

( the declare line is because of complaining typescript compiler)

3. changed private stepper: Stepper to private stepper:any

Doing so, you loose Stepper typings but you make the constructor work.

I'm no typescript expert so I actually don't know why this is working, hope it helps on solving the issue.

Hi @viniciuscst,

Can you include a live demo of the problem ? You can create a reduced test case via Stackblitz and report back with your link.

1. added `esModuleInterop": true` to compilerOptions in tsconfig.json

Thanks so much, this help me a lot!
