Error with Gem Outdated command

(realized this should have been posted here, not the Rails group…)

Trying to run ‘gem outdated’ on OS X (10.6.3) and I’m getting:

sudo gem outdated
ERROR: While executing gem … (NoMethodError)
undefined method `first’ for nil:NilClass

Here’s my info:

john$ gem env

Doing a ‘sudo gem update’ does work fine (it just updated a couple
fine).

Anyone? Thanks.

Not one to bump topics, but I’m still getting this error… and it’s been
2 months…

Thanks

a little more information about the gem outdated problem, by adding a
couple print lines to outdated_command.rb, its the devise gem thats
failing.

<Gem::Dependency type=:runtime name=“devise” requirements=">= 1.2.rc">

  dep = Gem::Dependency.new local.name, ">= #{local.version}"
  puts dep.inspect
  remotes = Gem::SpecFetcher.fetcher.fetch dep
  remote = remotes.last.first

undefined method `first’ for nil:NilClass

Perhaps the SpecFetcher doesnt know what to do with 1.2.rc.
