After adding react-native nothing is working, or showing

So, here’s the situation:
I’m starting a new app, get a couple things set up (CSS, a little templating), add react and react-native, then suddenly:
-localhost is a blank screen no matter what I do - all work is “not showing” for all intents and purposes.
-ENDLESS unresolved modules (see below).
-this: “=> Client modified -- refreshing (x6)” -(It happens with only 1 pending save too, not just multiples, and it never refreshes and restarts the server, at all, btw).

Why is this happening? I didn’t want to bother the community with my issues, but I’ve spent WAY too much time trying to fix this, and there’s nothing that I can find that is exactly the same issue, or even mentions any problems with react-native.
What I HAVE found is about missing modules for other things, and supposedly you can ignore these warnings. But my real dilemma is the broken app that is suddenly no more. Does anyone know what the problem might be? Honestly, I’m just starting to get into Meteor, so I’m probably doing something dumb.

Thank you in advance for your patience.

Oh, and here’s the list of “unresolved” modules:
