ruby_version's Issues

Pre-built gems found in gem release

Hello,

There are some .gem files under the pkg directory in the gem release archive. I believe this to be an oversight?

I've used the following snippet to get rid of them while packaging the package for GNU Guix:

(add-after 'extract-gemspec 'delete-gem-files
                          ;; There are some pre-built files in the source, and
                          ;; registered in the .gemspec.
                          (lambda _
                            (delete-file-recursively "pkg")
                            (substitute* "ruby_version.gemspec"
                              (("\"pkg/ruby_version-1.0.0.gem\".freeze, ")
                               "")
                              (("\"pkg/ruby_version-1.0.1.gem\".freeze, ")
                               ""))))

Thank you!
