Appears that deleting your installation's "rake.gemspec" file is enough. http://gist.github.com/519744 Perhaps rubygems doesn't know how to remove the previous version .gemspec file, since it lacks any version info? -r ---------------------------------------- http://redmine.ruby-lang.org/issues/show/3677 ---------------------------------------- http://redmine.ruby-lang.org
