jQuery UI: "base is not a constructor"

Question

I've installed jQuery and jQuery UI with npm. Upon attempting to require('jquery-ui/ui/widgets/selectable') in one of my own JS modules, I get the following error message:

TypeError: base is not a constructor (widget.js:108)

What am I missing?

Also had this problem with jQRangeSlider 5.5.0. Your solution works :) – Oriane

Answer 1

To solve the issue, I also had to require('jquery-ui/ui/widgets/mouse') which is a dependency for selectable but not loaded automatically when requiring the latter.

And the same thing with yarn! – Cannabis
