Question

I am trying to install acts_as_commentable_with_threading. I have added “gem ‘acts_as_commentable_with_threading'” to my Gemfile.

When I run “bundle install” from the command line I get the following.

Fetching source index for http://rubygems.org/
Bundler could not find compatible versions for gem "activerecord":
  In Gemfile:
    acts_as_commentable_with_threading depends on
      activerecord (~> 3.0.0)

    rails (= 3.1.0) depends on
      activerecord (3.1.0)

So acts_as_commentable_with_threading won’t work with activerecord 3.1.0? I am not sure how to workaround this?

Thanks

Answer 1

Currently, you can’t work around it, because acts_as_commentable_with_threading is dependent using ~> 3.0.0 which means >= 3.0.0 but < 3.1 (ref: http://gembundler.com/rationale.html – section “Updating a Dependency”)

The only options are to:

• downgrade Rails to 3.0 or
• not use this gem, because it’s support is not up to date w/the lates version of activerecord, according to the author
