我在 Mountain Lion 上的 rails 4.0 和 ruby 2.0 环境中使用 Mongoid 4.0 和 mongoDB v2.4.5。当我运行我的 rspec 测试时：
require 'spec_helper'
# This is a sample spec file, showing an initial effort to document a Ruby
# class or module (in this case, the Array class) based on the documentation
# at http://ruby-doc.org/.
describe Array do
describe '#new' do
it "should return the empty array" do
let(:array) { Array.new(3) }
end
end
end
这就是我得到的
An error occurred in an after hook
Mongoid::Errors::NoSessionsConfig:
Problem:
No sessions configuration provided.
Summary:
Mongoid's configuration requires that you provide details about each session that can be connected to, and requires in the sessions config at least 1 default session to exist.
Resolution:
Double check your mongoid.yml to make sure that you have a top-level sessions key with at least 1 default session configuration for it. You can regenerate a new mongoid.yml for assistance via `rails g mongoid:config`.
Example:
development:
sessions:
default:
database: mongoid_dev
hosts:
- localhost:27017
occurred at /usr/local/var/rbenv/versions/2.0.0-p195/lib/ruby/gems/2.0.0/bundler/gems/mongoid-06b708d37cde/lib/mongoid/sessions/factory.rb:61:in `create_session'

Mongo 似乎表现得非常正常。我该如何解决？
