I am trying to use Twitter's Typehead with Bloodhound, via NPM, and am getting the above error. I have seen other questions (and fixes) which are similar, but don't involve NPM.
I am using Laravel 5.5 and Webpack. First, I installed typeahead.js and bloodhound.js using NPM. I required both packages in my bootstrap.js and ran npm run dev. Typeahead worked fine, but I got the error when I tried to issued new Bloodhound().
I then uninstalled these packages and installed https://github.com/corejavascript/typeahead.js. Again, I ran npm run dev, but still got the error above.
UPDATE: I just installed typeahead.js using bower, then included it directly in to my files. That worked fine.
