go get: installing executables with 'go get' in module mode is deprecated.
  To adjust and download dependencies of the current module, use 'go get -d'.
  To install using requirements of the current module, use 'go install'.
  To install ignoring the current module, use 'go install' with a version,
  like 'go install example.com/cmd@latest'.
  For more information, see https://golang.org/doc/go-get-install-deprecation
  or run 'go help get' or 'go help install'.
