Thank you for the report!

I guess I know the root cause

Does it work with this?

go-licenses check .

[Bobgy]

Hmm, my guess was wrong. Can you share more about your project setup?

Are you using GOPATH or go modules?

[Bobgy]

I think I fixed it, but the error means that you might not be using go modules yet.
Can you confirm?

You can try installing go-licenses from master by go install github.com/google/go-licenses@master.

[Bobgy]

Released v1.1.1 with the fix: https://github.com/google/go-licenses/releases/tag/v1.1.1.

[gregorypa]
