Can't start Solr-Server after installation: bundle exec rake sunspot:solr:start rake aborted! undefined method `map' for :needs:Symbol

Question

After I installed sunspot_rails I'm getting this error "undefined method `map' for :needs:Symbol" if I run bundle exec rake sunspot:solr:start

I don't know how to pinpoint this error.. If you have any suggestions please let me know

It seems sunspot_rails 1.2.1 doesn't work with rails 3.2.16. I get no error with last version of sunspot_rails
