Package doesn't seem to be usable

[SoulflareRC]

I installed the package using npm install react-markdown-toc, but I couldn't import anything from the package.
I did

import { TOC } from 'react-markdown-toc/client'

but I got

Server Error
Error: Cannot find module '..\node_modules\react-markdown-toc\dist\components\client' imported from ..\node_modules\react-markdown-toc\dist\client.js

I created a minimal example repository, please see if it solves your error.
