Seems like you just need to update packages used in the demo.

Could you please. provide a complete demo of your app, so the problem could be tested locally.

#3

there is no demo I just followed the steps in the guide located https://github.com/DHTMLX/optimus-starter-app/tree/guide/step-1

I downloaded the files from Github placed them into a folder on the server and typed
npm install and I get the message you see above. I have tried it server time with the same results

The older version 5 of DHTMLX was much easier to use.
