I have the same problem. Created a new Rails project as per instructions from neo4jrb and neo4j-rspec READMEs. Upon calling rake neo4j:migrate RAILS_ENV=test, I get the following error:

NameError: uninitialized constant Neo4j::RSpec::Matchers

I have set up a repository that replicates the problem at my end:
