Is this an error and what does it mean?

First off, unrelated to the error, do not build with sudo.

Anyways, that's an error with the newgrounds library, you can try to fix it by reinstalling it (haxelib install newgrounds)

I'm gonna try again this time without sudo, I also updated the newgrounds library

it's giving me this error now
