Unable to release my gem to github

I'm confused as to what is happening here:

$ sudo rake install
(in /Users/****/code/parsley)
WARNING:  no rubyforge_project specified
WARNING:  description and summary are identical
  Successfully built RubyGem
  Name: parsley
  Version: 0.1.1
  File: parsley-0.1.1.gem
Executing "ruby -S gem install ./pkg/parsley-0.1.1.gem":
ruby -S gem install ./pkg/parsley-0.1.1.gem
Successfully installed parsley-0.1.1
1 gem installed
Installing ri documentation for parsley-0.1.1...
Installing RDoc documentation for parsley-0.1.1...

But I notice I no longer have a clean repo, so:

 $ git status
# On branch master
# Changes not staged for commit:
#   (use "git add/rm <file>..." to开发者_运维百科 update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#   deleted:    parsley-0.1.1.gem
#
no changes added to commit (use "git add" and/or "git commit -a")

This seems strange to me. 0.1.1 is the current release, so I'm not sure why the gem would be deleted. I guess in preparation for it to be recreated? So I commit. But then when I go to do rake release, I get this error:

$ rake release
(in /Users/****/code/parsley)
Pushing master to origin

parsley.gemspec is valid.

I am releasing this to a private repo, that might be important here because I was able to release a test gem to a public repo. Any ideas?

I found this tutorial on publishing private gems, and everything worked.
