Error with Gem Outdated command

Trying to run ‘gem outdated’ on OS X (10.6.3) and I’m getting:

sudo gem outdated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
RubyGems Environment:

  • RUBYGEMS VERSION: 1.3.7
  • RUBY VERSION: 1.8.7 (2009-06-08 patchlevel 173)

    • /Users/john/.gem/ruby/1.8

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8

  • GEM CONFIGURATION:
    • :update_sources => true
    • :verbose => true
    • :benchmark => false

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

I can’t help, but you’ll get more luck on the Rubygems mailing list or
the main Ruby list.
