Rails 4 Mercur-Rails dependency error railties

Question

I am getting this error when doing a bundle update. How do I resolve this. I know mercury can work on new version of railties, I just don't know how to resolve this issue.

[root@sxxx xxx]# bundle update

Bundler could not find compatible versions for gem "railties":
  In Gemfile:
    mercury-rails (~> 0.9.0) java depends on
      railties (~> 3.2) java

    rails (= 4.0.0) java depends on
      railties (4.0.0)

Answer 1

It's probably outdated question but I'll post this answer for anyone else who has similar problem.

You should change your Gemfile and use github repo as a mercury-rails gem source. So instead of:

gem 'mercury-rails', '~> 0.9.0'

you should have sth. like this:

gem 'mercury-rails', git: 'https://github.com/jejacks0n/mercury'

I'm not sure why because 0.9.0 is the latest release but what is the most important thing is that will work :)
