    This is a RubyGems issue. Ruby 1.9 ships with an outdated RubyGems and you can't upgrade it.

    http://redmine.ruby-lang.org/issues/show/2355

    Fortunately, you can ignore the warnings.

    I am having a similar issue where running "rails -v" (inside of a rails project only) or running script/rails results in a lot of "WARNING: Invalid .gemspec format" for example:

    WARNING: #<NoMethodError: undefined method >' for nil:NilClass><br/>

    -- encoding: utf-8 --

    Gem::Specification.new do |s|
    s.name = %q{abstract} s.version = "1.0.0"

    s.required_rubygems_version = nil if s.respond_to? :required_rubygems_version= s.authors = ["makoto kuwata"] s.cert_chain = nil s.date = %q{2006-03-12} s.description = %q{'abstract.rb' is a library which enable you to define abstract method in Ruby.} s.files = ["lib/abstract.rb", "test/test.rb", "README.txt", "ChangeLog", "setup.rb", "abstract.gemspec"] s.homepage = %q{http://rubyforge.org/projects/abstract} s.require_paths = ["lib"] s.required_ruby_version = Gem::Requirement.new("> 0.0.0") s.rubygems_version = %q{1.3.5} s.summary = %q{a library which enable you to define abstract method in Ruby} s.test_files = ["test/test.rb"]

    if s.respond_to? :specification_version then

    current_version = Gem::Specification::CURRENT_SPECIFICATION_VERSION
s.specification_version = 1

if Gem::Version.new(Gem::RubyGemsVersion) >= Gem::Version.new('1.2.0') then
else
end

    else end end
    WARNING: Invalid .gemspec format in '/usr/local/Cellar/ruby/1.9.1-p378/lib/ruby/gems/1.9.1/specifications/abstract-1.0.0.gemspec'

    This is followed by a couple thousand lines of output and whereas I can ignore them, it's still very annoying.

    Please also have a look on https://rails.lighthouseapp.com/projects/8994/tickets/3863-rails-30...

    This is a ruby 1.9 issue with an easy fix, but we wanted to treat it in other places.

    as pointed out by Balazs Nagy the "warning: already initialized constant" comes from Ruby cruft. removing the old library directory and starting with a fresh install removes those warnings.

    note, this does not fix the verbose "Invalid .gemspec format in" warnings.

    here's approximately what I did on OS X (snow leopard).

    gem list --no-version > gem_list.txt
sudo mv /usr/local/lib/ruby /usr/local/lib/ruby-old
wget ftp://ftp.ruby-lang.org/pub/ruby/snapshot.tar.bz2
# install
sudo su
gem install tzinfo builder memcache-client rack rack-test rack-mount erubis mail text-format thor bundler i18n
gem install rails --pre
gem install sqlite3-ruby
env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
# install remaining gems

    The new bundler version 0.9.4 solves the first "Invalid .gemspec format" problem.

    The second RubyGems problem can be solved by a simple

    sudo gem uninstall rubygems-update

    i'll confirm what Christian said in regards to the "Invalid .gemspec format" problem being solved for rails server and rails console
