Invalid gemspec because of the date format in specification
Here is the way I fix the “invalid date format in specification” error: 1.) Go to the specifications folder located at: /usr/local/lib/ruby/gems/1.8/specifications/ 2.) Find the spec that is causing the problem. 3.) Change s.date = %q{2011-05-21 00:00:00.000000000Z} to s.date = %q{2011-05-21} That’s a WIN for me! Good Luck
