My issue was occurring because I was attempting to use devise in a custom rails engine in my project.
I updated the code above so that errors weren't thrown and but ultimately decided to remove the rails engine and move associated code back into the main project.
class Rails::Plugin::GemLocator
# find the original that we patch in rails/lib/rails/plugin/locator.rb:80
def plugins
specs = Bundler.definition.specs_for([]).to_a
gem_specs = Gem.loaded_specs.values.select do |spec|
spec.loaded_from && # prune stubs
# File.exist?(File.join(spec.full_gem_path, "rails", "init.rb"))
(File.exist?(File.join(spec.full_gem_path, "rails", "init.rb")) || File.exist?(File.join(spec.full_gem_path, "init.rb")))
end
specs += gem_specs
require "rubygems/dependency_list"
deps = Gem::DependencyList.new
deps.add(*specs) unless specs.empty?
deps.dependency_order.collect do |spec|
Rails::GemPlugin.new(spec, nil)
end
end
end
Glad that you found the solution yourself. The code above is for a quite ancient bundler version (0.9.5 I belive) so I'm not too suprised that it does not work with the current version anymore.
