I ran into this today when trying to do a license scan of the https://github.com/crossplane/crossplane project.

go install github.com/google/go-licenses@latest

git clone https://github.com/crossplane/crossplane.git

cd crossplane

go-licenses csv ./...

That shows many error messages like the following in the output:

Looks like it's mostly the standard library. I was able to get some license scan output after running go install github.com/google/[email protected]. Is there a different way I should be invoking latest to work successfully?

I have faced the same issue runnning go-licenses on a proprietary project, despite the project having a go.mod.
