Error 401 in windows command prompt?

When use npm run dev, which scripts the "node app.js" to run. But when I try to run it, I get this error code:

C:\Users\rfasc\Dropbox\Hackathon\HackCuTwitter>npm run dev

> Tweeter@1.0.0 dev C:\Users\rfasc\Dropbox\Hackathon\HackCuTwitter
> node app.js

Error: Status Code: 401

I also get this error when I try to run sudo at all when I use bash in the cmd:

ryryfasch@LAPTOP-9TPB1OJ6:/mnt/c/Users/rfasc/Dropbox/Hackathon/HackCuTwitter$ sudo i
sudo: unable to resolve host LAPTOP-9TPB1OJ6

I have tried looking up many fixes and can't figure it out. Thanks.
