jszip module uses "streams" which are included in Node.js but are not included in a browser.
Bundlers (for example, webpack) seem to have their own internal list of modules for which they have a built-in substitution and stream module seems to be one of them.
https://unpkg.com/jszip@3.1.5/lib/readable-stream-browser.js
So, when Webpack sees require('stream') it replaces it with its own substitute.
Seems that you're using "browserify" bundler which substitutes require('stream') with stream-browserify module.
And stream-browserify uses readable-stream internally which uses a native Node.js module called util which is not available in a browser too.
Now, I guess Webpack would substitute util with something else but Browserify seems to not do that.

See the original issue in readable-stream repo:
nodejs/readable-stream#356
I left my comment there.
