Rails服务器将无法启动

Question

When I try to run my rails server, I get the following error:

/Users/yedidyaweiner/.rbenv/versions/2.1.2/lib/ruby/gems/2.1.0/gems/activerecord-      4.1.1/lib/active_record/associations/builder/association.rb:63:in `initialize': undefined   method `arity' for :versions:Symbol (NoMethodError)

Thank you in advance.
