config.gem dependencies broken?

Hello there,

I am having some strange problems with my project''s gem dependencies
on my staging server and really don''t know where this is coming from.

My config.gem entries in the environment.rb file are the following:

--- snip ---

  config.gem "geonames"
  config.gem "yelp"
  config.gem ''oauth'', :version => ">= 0.2.1"
  config.gem "vikinggem", :lib => "viking"
  config.gem "RedCloth", :lib => "redcloth", :version
=> ">= 4.0"
  config.gem ''pager-retardase_inhibitor'', :lib =>
''retardase_inhibitor'', :source =>
''http://gems.github.com''
  config.gem ''right_aws''
  config.gem ''mime-types'', :lib =>
''mime/types''
  config.gem ''json''
  config.gem ''hpricot''
  config.gem ''uuidtools''
  config.gem ''chronic''
  config.gem ''htmlentities''

--- snip ---

Now when I do a gem list --local on the affected machine, it looks
like this:

*** LOCAL GEMS ***

--- snip ---

actionmailer (2.2.2)
actionpack (2.2.2)
activerecord (2.2.2)

Nooow when I do a rake gems in my project''s folder, I get the
following:

--- snip ---

First of all, why is it saying hoe/rubyforge is missing (as they are
listed in the gems list --local list) & secondly, why''s there a
nil.dependencies exception?


Apparently this also does break my app, since all views that rely on
acts_as_textiled throw a "ActionView::TemplateError (uninitialized
constant Err::Acts::Textiled::ClassMethods::RedCloth) .." exception.


I already did a sudo gem uninstall/clean/install of all gems.. no
change :-/

joerg@staging:~$ ruby -v
ruby 1.8.7 (2008-08-11 patchlevel 72) [x86_64-linux]
joerg@staging:~$ rails -v
Rails 2.2.2

Hrm. Any ideas? Suggestions? I am seriously kinda lost here...


Thanks,
-Joerg

Re: config.gem dependencies broken?

Hi Joerg,

This is a real bug and it has been solved. See the following thread.
http://groups.google.com/group/rubyonrails-core/browse_thread/thread/73f21c47d114b88e


To solve the problem apply the patch on:
http://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/1464

The shortcut way is to add a line to:
/usr/lib/ruby/gems/1.8/gems/rails-2.2.2/lib/rails/gem_dependency.rb

    def dependencies
      return [] if framework_gem?
      return [] if specification.nil? # <= THE NEW LINE
      all_dependencies = specification.dependencies.map do |dependency|


Hopefully soon there will be an updated gem.

Have fun,

Sander

Re: config.gem dependencies broken?

Sander,

ahhh I see.. thank you. I could workaround this issue by explicitely
specifiying each of my gems dependencies before the actual gems:
