can't work in ts

[taven-liu]

Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object. Check the render method of Sidebar.

Hey @taven-liu. This repository is a fork of https://github.com/souhe/reactScrollbar with a really little difference to suit our needs, so you'll find a better support here.

But related to your issue, you should use ScrollArea as the default import, like this:
import ScrollArea from 'react-scrollbar';
or
let ScrollArea = require('react-scrollbar').default;
