Activemessaging caused infinite loop in my Rails app - ruby-on-rails

Question

In my rails app, activemessaing caused an infinite loop, e.g. when I run bundle install, an error message is given:
"Your Gemfile requires gems that depend on each other, creating an infinite loop. Please remove gem 'activemessaging' and try again."
Any ideas?

Answer 1

As the message suggests, the problem is caused by the infinite loop dependency, e.g. activemessaging depends on itself. Check the gem spec in activemessaging to see if there is a self dependency defined.

Answer 2

I managed to get it fixed.
Just refer activemessaging to my forked version:
gem "activemessaging", :git => "https://github.com/digital-york/activemessaging.git"
The changes I've made is just to comment out self dependencies in the gem spec.
