malformed module path "io/fs"

[nextfour-back-sabina]

I used the command:

go get github.com/google/[email protected]

And the download started. However, it was interrupted by thiss error message:
build github.com/google/addlicense: cannot load io/fs: malformed module path "io/fs": missing dot in first path element

This is the whole download:

$ go get github.com/google/[email protected]

What version of go are you using? addlicense requires go1.16, which is when the io/fs package was added.

I'm assuming this is simply a go versioning issue. If its something else, please feel free to provide more info.
