Local Melpa Build Error

I work behind a firewall so I need a local melpa. I use the following recipe: ``` >more spacemacs-theme (spacemacs-theme :url "/home/myname/.emacs.d/packages/src/spacemacs-theme/" :fetcher git) ``` I get the following error ``` Error: package-build-error "Missing library \"spacemacs-theme.el\" matching package name ‘spacemacs-theme’" signal(package-build-error "Missing library \"spacemacs-theme.el\" matching package name ‘spacemacs-theme’") (let ((message (apply #'format-message format-string args))) (package-build--log package message) (signal 'package-build-error message)) ``` After reading it may be because it is a theme and not a package. Any ideas about why this is happening and how to correct it?
