ReferenceError: Can't find variable: Set

Hey,

so I am getting the following error:

ReferenceError: Can't find variable: Set

  http://localhost:8080/js/webcomponents-lite.js:147
  http://localhost:8080/js/webcomponents-lite.js:192

The actual code is: new Set("…

Any idea why this shows up? Is it possible the phantomjs version does not support Set? Can I avoid this somehow?

Can I provide any more information that could help?

Thanks.

The latest version of PhantomJS does not support ES2015 Set.

You can try the experimental branch of uncss that uses jsdom instead of PhantomJS by installing uncss-jsdom instead. See #280
