Webix pro yarn install

hi, i try to install webix pro packages through yarn package manager.
i do:
yarn login --registry=http://npm.webix.com --scope=@xbs
it ask me username and email ( no password )

and after yarn can’t find webix_pro on:
yarn add @xbs/webix-pro

can you tell me how to install through yarn please?

Could you please send us a log with a problem. You can send it by mail to support@webix.com

There is an open issue for the yarn

Just use npm login --registry=http://npm.webix.com --scope=@xbs for initial login, after which you can use yarn for any other operations with package
