undefined local variable or method `version_requirements’ for # (NameError)

Posted February 16, 2011 under Rails

So I upgraded to the latest rubygems the other day…only to be presented with this wonderful little error!

undefined local variable or method `version_requirements' for #<Rails::GemDependency:0x1022cc1c8> (NameError)

I thankfully came across this comment on a gist on github of someone having the same error.

The solution is fairly simple. Just run the following commands to go back to the previous version of rubygems and you should be fine:

$ gem install rubygems-update -v='1.4.2'
$ gem uninstall rubygems-update -v='1.5.0'
$ update_rubygems

That simple revert seems to fix any issue I have with running Rails 2.3 applications. If anyone knows more about the issue and how we can fix it to use rubygems 1.5.x with Rails 2.3 that would be great!

Thanks for sharing! =)
Problem solved, but I just ran the install command and update.

Thank you very much.
@Philip, I have to uninstall the 1.5.x ruby gem.

Upgrading from Rails 2.3.2 to 2.311 allowed me to use RubyGems 1.5.2 without problems.

Thanks for the feedback. I use a mix of Rails 2.3 and 3.0 applications so upgrading went haywire for 2.3 but not 3.0. It might just be that our project is using an older version of Rails 2.3 and we should upgrade it.

Thanks, this was a big help getting an old rails 2.2.2 app running on a new machine!

So if I get the response

RubyGems 1.4.2 installed
ERROR:  While executing gem ... (Errno::ENOENT)
    No such file or directory - README

What else do I need to do?

Thank you it’s working

Rails 2.3.5 not working with 1.5.0 gems

fixed by revert to 1.4.2

– RUBYGEMS VERSION: 1.4.2
– RUBY VERSION: 1.8.7 (2008-08-11 patchlevel 72) [x86_64-linux]

I’m using redmine 1.1.1 and I just upgraded Rails to 2.3.11 and it fixed this for me.

This hack worked for me:
Phillip Koebbe from Ruby on Rails suggested inserting following code between bootstrap and initialize section of enviroment.rb. And it works.

if Gem::VERSION >= “1.3.6″
module Rails
class GemDependency
def requirement
r = super
(r == Gem::Requirement.default) ? nil : r
end
end
end
end
