I came across a bug.
What is the current behavior?:
I copied the example code and found that Icannot initialize the PixivApp instance. However, when I switched my current ES6 import method (import PixivAppApi from 'pixiv-app-api' ) to CommonJS module(const PixivAppApi =require('pixiv-app-api' )), it works.

The console log is:

 this.pixiv = new PixivAppApi(this.config.username as string, this.config.password as string, {
                     ^
TypeError: pixiv_app_api_1.default is not a constructor

What is the expected behavior?:
Using ES6 import works.
Suggested solution:
I've checked the source code and found no obvious error.
