Well, after investigation and the codebase is cmd/go/internal/modget/get.go:346 as the following:

            if !strings.Contains(path, "...") {
                pkgPath := modload.DirImportPath(filepath.FromSlash(path))
                if pkgs := modload.TargetPackages(pkgPath); len(pkgs) == 0 {
                    abs, err := filepath.Abs(path)
                    if err != nil {
                        abs = path
                    }
                    base.Errorf("go get %s: path %s is not a package in module rooted at %s", arg, abs, modload.ModRoot())
                    continue
                }
            }

            if path != arg {
                base.Errorf("go get %s: can't request explicit version of path in main module", arg)
                continue
            }

now it works by go get -v ...

Please fill out the complete issue template:

• List the actual commands that you ran (with any sensitive paths anonymized).
• Show the actual output as text (again with any sensitive paths anonymized).

go get -v all should also work.
