Rails的LocalJumpError：沒有給出的塊（yield）

很多我的規格給了我上面的錯誤，但我不知道爲什麼。？Rails的LocalJumpError：沒有給出的塊（yield）

# Model 
describe Notification do 
    context "has valid db fields" do 
    subject { Factory.build(:notification)} 
    it { should be_valid } 
    it { should have_column(:title).with_options(:null => false, :type => :string)} 
    it { should have_column(:content).with_options(:null => false, :type => :string)} 
    it { should have_column(:sent_at).with_options(:type => :date)} 
    it { should have_column(:created_at).with_options(:null => false, :type => :date)} 
    it { should have_column(:updated_at).with_options(:null => false, :type => :date)} 
    end 
end

看起來像你有一個額外的'結束' – Kelvin

你可以發佈堆棧跟蹤嗎？我沒有看到任何會導致此處丟失塊錯誤的內容。（即使有額外的結束，這會導致意外的關鍵字錯誤。） –

Kelvin，Thx。我糾正了帖子，以匹配我的實際代碼。不是問題。 –

我認爲這實際上是由於沒有在我的Gemfile「早該」自定義匹配器！
