我试图在RSpec中存根Time.now,如下所示:

it "should set the date to the current date" do
    @time_now = Time.now
    Time.stub!(:now).and_return(@time_now)

    @thing.capture_item("description")
    expect(@thing.items[0].date_captured).to eq(@time_now)
end

这样做时我收到以下错误:

 Failure/Error: Time.stub!(:now).and_return(@time_now)
 NoMethodError:
   undefined method `stub!' for Time:Class

知道为什么会发生这种情况吗？
