Hi, i´m Sergio, and I am trying to run your application from NPM, but i've got this error:

npm ERR! 404 Not Found - GET https://registry.npmjs.org/three-vue-viewport - Not found
npm ERR! 404
npm ERR! 404  'three-vue-viewport@latest' is not in the npm registry.
npm ERR! 404 You should bug the author to publish it (or use the name yourself!)

is there any other way to get this running? thank you
