rspec undefined方法`receive'用于expect语法

Question

更改有效的测试,例如:

describe "a" do
  it "does part A" do
    it "does not wait if not run in parallel" do
      ParallelTests.should_not_receive(:sleep)
      ParallelTests.wait_for_other_processes_to_finish
    end
  end
end

至

describe "a" do
  it "does not wait if not run in parallel" do
    expect(ParallelTests).to_not receive(:sleep)
    ParallelTests.wait_for_other_processes_to_finish
  end
end

给

 Failure/Error: expect(ParallelTests).to_not receive(:sleep)
 NoMethodError:
   undefined method `receive' for 
 #<RSpec::Core::ExampleGroup::Nested_1::Nested_3:0x00000002874158>

这是一个例子.发生在许多地方,共同的主题是,它总是要改变.should_receive到expect().to receive

Gemfile的版本为2.4的rspec

怎么修？

将Gemfile更改为2.14,例如gem 'rspec', '2.14'并执行bundle
