`requirement': wrong number of arguments

[sleepycat]

I was working my way through the install tutorial and as they
mentioned I ran into the

undefined local variable or method `version_requirements'

problem.

I did the code they specifed into my environment.rb like this:


# Specifies gem version of Rails to use when vendor/rails is not
present
RAILS_GEM_VERSION = '2.3' unless defined? RAILS_GEM_VERSION

# Bootstrap the Rails environment, frameworks, and default
configuration
require File.join(File.dirname(__FILE__), 'boot')

#
#Added to prevent the "undefined local variable or method
`version_requirements' problem
#
if Gem::VERSION >= "1.3.6"
module Rails
class GemDependency
def requirement
r = super #(r == Gem::Requirement.default) ? nil : r
end
end
end
end

Rails::Initializer.run do |config|
gitorious_yaml = YAML.load_file(File.join(RAILS_ROOT, "config/
gitorious.yml"))[RAILS_ENV]
raise "Your config/gitorious.yml does not have an entry for your
current Rails environment. Please consult config/gitorious.sample.yml
for instructions." unless gitorious_yaml

# Settings in config/environments/* take precedence over those
specified here.
# Application configuration should go into files in config/
initializers
# -- all .rb files in that directory are automatically loaded.
# See Rails::Configuration for more options.



But I am getting this error:

Anyone have any thoughts on what the problem is?

I am running rubygems 1.5.2

I had the same problem; I think there is a typo in the instructions.
Try putting a line break between r = super and (r ==
Gem::Requirement.default) ? nil : r. It should look like a snippet I
found here (which ultimately helped me figure this out.)

http://www.redmine.org/issues/7516

I'm still not done working through the instructions, but this change
did appear to allow the gems::install command to work as intended.

Good luck
Philip

An alternative approach is to downgrade RubyGems and use 1.4.x.

Cheers,
