我目前在执行以下 rspec 命令时得到以下输出：

请参阅文件 temperature_spec.rb 的源代码

require "temperature"

describe "temperature conversion functions" do

  describe "#ftoc" do

    it "converts freezing temperature" do
      ftoc(32).should == 0
    end

    it "converts boiling temperature" do
      ftoc(212).should == 100
    end

    it "converts body temperature" do
      ftoc(98.6).should == 37
    end

    it "converts arbitrary temperature" do
      ftoc(68).should == 20
    end

  end

  describe "#ctof" do

    it "converts freezing temperature" do
      ctof(0).should == 32
    end

    it "converts boiling temperature" do
      ctof(100).should == 212
    end

    it "converts arbitrary temperature" do
      ctof(20).should == 68
    end

    it "converts body temperature" do
      ctof(37).should be_within(0.1).of(98.6)
      # Why do we need to use be_within?
      # See http://www.ruby-forum.com/topic/169330
      # and http://en.wikipedia.org/wiki/IEEE_754-2008
      # and http://en.wikipedia.org/wiki/Double_precision_floating-point_format
      # Also, try "puts 0.5 - 0.4 - 0.1" -- pretty crazy, right?
    end

  end

错误消息告诉您在与文件temperature.rb相同的目录中没有名称为 的temperature_spec.rb文件。
