tzinfo conflict with mongoid and rufus-scheduler

I try to use mongoid 3.x together with rufus-scheduler 2.x and im always getting a gem conflict over tzinfo.

Unable to activate mongoid-3.1.4, because tzinfo-1.0.1 conflicts with tzinfo (~> 0.3.22)

Looks like mongoid has some dependency on some legacy tzinfo version.

How can I solve this problem?

Solution

  • In your Gemfile, specify the version of TzInfo that suits Mongoid, before Mongoid and before rufus-scheduler (rufus-scheduler accepts any version of TzInfo).

    source 'https://rubygems.org'

gem 'tzinfo', '0.3.22'
gem 'mongoid', '3.1.4'
gem 'rufus-scheduler'

    UPDATE

    Updated rufus-scheduler 2.0.x so that it accepts >= 0.3.22 (https://github.com/jmettraux/rufus-scheduler/commit/18c98010)

    Unfortunately, can't seem to be able to push to RubyGems.org for now (it goes 500).

    Until I find a workaround, you can point to that new rufus-scheduler with

    gem 'rufus-scheduler', :git => 'git://github.com/jmettraux/rufus-scheduler.git', :branch => 'two'

    UPDATE

    Could push rufus-scheduler 2.0.24 to rubygems https://rubygems.org/gems/rufus-scheduler

    It should be OK now.
