go-licenses: golang.org/x/sys and other packages don't seem to work

I’m walking through the dependencies in my go.mod and I find that the golang.org/x/ repositories give me trouble:

% go-licenses csv golang.org/x/sys
Error: errors for ["golang.org/x/sys"]:
golang.org/x/sys: -: module golang.org/x/sys@latest found (v0.0.0-20200420163511-1957bb5e6d1f), but does not contain package golang.org/x/sys

  licenses csv <package> [flags]

Is there a trick to this? Advice?

Sure: I am on macOS 10.16.0 Big Sur and I have tried with different values for the GO111MODULE env variable.

if installing via go install golang.org/x/sys@latest I get a combination of “no Go files in ~/go/src/golang.org/x/sys” and “module golang.org/x/sys@latest found (v0.1.0), but does not contain package golang.org/x/sys” according to whether or not I set GO111MODULE to explicit values.

if importing golang.org/x/sys in a module and running go mod tidy I get
../../go/pkg/mod/golang.org/x/sys@v0.0.0-20200918174421-af09f7315aff/unix/zsyscall_darwin_arm64.1_13.go:40:3: /go:linkname must refer to declared function or variable

The commands you ran do not relate to go licenses though.

Note golang.org/x/sys is not a go package, that’s why those commands failed. There are go packages with golang.org/x/sys as prefix.

Here is a repo showing this problem: https://github.com/dcormier/go-licenses (complete with the requested go.mod file)

Here is the result of running the command in that repo:
