"TypeError: jsdom.jsdom is not a function" with paper-node.js in npm paper module

I have installed webppl-agents library (along with webppl and webppl-dp) and am trying to run the command line test, but I'm running into some trouble. It appears there is a dependency issue with jsdom from the npm paper module (1) (2) (3) (4), but I haven't been able to get a complete handle on the issue at this point.

Does anybody know what's going on here? Do I just need to use a newer version of paper?

 PS C:\Users\user\.webppl\node_modules\webppl-agents> webppl --require webppl-dp --require . tests/tests.wppl
C:\Users\user\.webppl\node_modules\webppl-agents\node_modules\paper\dist\paper-node.js:10835
        document = jsdom.jsdom('<html><body></body></html>'),
                         ^

TypeError: jsdom.jsdom is not a function

There has been some breaking changes recently. The following way of initializing jsodm, document and window fixed it for me: 

import jsdom from 'jsdom';  
const {JSDOM} = jsdom;  
const {document} = (new JSDOM('<!doctype html><html><body></body></html>')).window;  
global.document = document;  
global.window = document.defaultView;
