def self.pack_for_installation
  # Homebrew assumes the buildpath/testpath will always be disposable
  # and from npm 5.0.0 the logic changed so that when a directory is
  # fed to `npm install` only symlinks are created linking back to that
  # directory, consequently breaking that assumption. We require a tarball
  # because npm install creates a "real" installation when fed a tarball.
