@voxelize/client is not in this registry

[tomhsiao1260]

Hi, I've followed Voxelize official tutorial, however, when I clone this repo and then run npm install, the following error occurs:

npm ERR! 404 Not Found - GET https://registry.npmjs.org/@voxelize%2fclient npm ERR! 404 '@voxelize/client@1.3.95' is not in this registry.

Seems npm itself cannot find this package, any advice on how can I use it correctly?
Thanks in advance.
