Activemessaging caused infinite loop in my Rails app

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?

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.
