Ionic Project Not Working on One Machine, Fine On Another

I have an ionic project I’m working on out of Dropbox. Using “ionic serve”, it compiles and runs perfectly on one laptop, but the exact same code base does not run correctly on another. Some styles do not appear to be loading with sass, and a JSON object which displayed perfectly on my other machine, does not pass successfully to the controller on my main machine. I’ve tried reinstalling/updating cordova, ionic, and node. None of that has made any difference. Does anyone have any suggestions? I’m at a loss as to how to troubleshoot this futher. This has got to be a problem with one of the tools on my local install, because if I run “ionic build android && ionic run android” it works perfectly fine on my phone.

OK, I think I’ve got this figured out. Somehow a local installation of gulp was not working correctly on my system. I reinstalled both gulp and sass and it worked.
