Vendored Gems Not Being Activated With Rake Tasks
Reported by John Dzak | March 10th, 2009 @ 10:24 PM
Observed in rails >=2.3 when rails gems are vendored.
When Rakefile calls boot.rb, load_initializer (for class VendorBoot) will stub gem specs, but will not add_gem_load_paths.
If you have another gem that requires a vendored gem, you will receive an error message like..
rake -T
rake aborted!
can't activate activesupport (>= 2.0.0, runtime), already activated activesupport-2.3.1
Before Fix
def load_initializer
require "#{RAILS_ROOT}/vendor/rails/railties/lib/initializer"
Rails::Initializer.run(:install_gem_spec_stubs)
end
After Fix
def load_initializer
require "#{RAILS_ROOT}/vendor/rails/railties/lib/initializer"
Rails::Initializer.run(:install_gem_spec_stubs)
Rails::Initializer.run(:add_gem_load_paths)
end

It would be more descriptive to run Rails::GemDependency.add_frozen_gem_paths directly, as that's whats accomplished here. Calling add_gem_load_paths implies that config.gem stuff is getting loaded, which is not the case.
I'm curious, however, how you encountered this error. What gems are you using, and do you have 'require' and/or 'gem' statements in your rake tasks?

Ah cool, thanks.
So we encounter this error when a rake tasks in our rails project loads another task which is housed in a gem we wrote. That task eventually calls require 'activesupport' and that is where we encounter the problem.
BTW, this will only happen if the 2.3.1 gems that are vendored are not installed in rubygems. We noticed the problem on a machine that only had the 2.2.2 gems installed.

Does add_frozen_gem_paths solve the problem? 2.3 is right around the corner, and it would be good to get a patch in.
