It looks like you have the jQuery declaration file but not the jQuery UI declaration file. It's available here: https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/jqueryui
Edit: Modern TypeScript development is installing packages through npm rather than downloading files manually. Install the declaration file with npm install --save @types/jqueryui
