ERRO[0000] Error: exit status 2   

I have tried uninstalling and reinstalling buffalo as well as removing my go directory and recreating everything. I have also confirmed that my $GOPATH is set properly and it is included in my $PATH.

Answer 1

As explained here, GOPATH is no longer supported by Buffalo. You either need to create your project somewhere else, or explicitly set the GO111MODULE environment variable to on.
