I'm developing on Ubuntu, I have installed the mongoid gem, and when I run the rails server, I get this error
/home/username/.rvm/gems/ruby-1.9.2-p180/gems/mongo-1.3.1/lib/mongo/connection.rb:518:in `connect': Failed to connect to a master node at localhost:27017 (Mongo::ConnectionFailure)
I remembered using a command like brew install but I am pretty clueless. Am I missing something? Thanks in advance!
