GEMS: GEMSPEC problem

Greetings:
I’m a Ruby/Rails/Cucumber neophyte.

Goal: To use Cucumber for automated testing of iOS (Objective-C)
applications.

Environment:

  1. Mac OS X & iOS simulation/OS X.
  2. ruby --version
    ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-darwin11]
  3. gem --verison
    1.3.7

I’m trying to install a cohesive ruby/gem library that simply work.
After I’ve installed a ‘frank-cucumber’ gem, everything went crazy.

Now I’m getting a string of diagnostic text with a warning after I
attempt to access a gem item. For example (abridged):

RicMac:~ Ric$ gem --list
WARNING: #<ArgumentError: Illformed requirement
["#YAML::Syck::DefaultKey:0x10f13dcc8 0.8.4"]>

-- encoding: utf-8 --

Gem::Specification.new do |s|
s.name = %q{cucumber}
s.version = “1.0.4”

s.required_rubygems_version = Gem::Requirement.new(">= 0") if
s.respond_to? :required_rubygems_version=
s.authors = [“Aslak Helles\303\270y”]


WARNING: Invalid .gemspec format in
‘/opt/local/lib/ruby/gems/1.8/specifications/cucumber-
1.0.4.gemspec’
rake aborted!


Question:

  1. How do I correctly manage my gems/ruby environment so the assorted
    .gemspecs are in sync?
  2. I have ruby 1.9 instance installed on my Mac OS X in addition to the
    default ruby v1.8.7.
    How do I manage both environments (with associated gem specs)?

In short…
I want to be able to type $>gem --version or $>cucumber --version
WITHOUT flagging ‘invalid…gemspec.’

Regards,
Ric.

rvm[1] should help you with the “managing your environments” issue.

I’m guessing your specific issue may be related to this post[2].
