RSpec:kernel_require.rb:45:在`require':无法加载这样的文件 - bowling.rb(LoadError)

Question

按照这里的例子:

http://rspec.info

然而它失败了:

kernel_require.rb:45:in `require': cannot load such file -- bowling.rb (LoadError)

即使我有一个bowling.rb文件.

有什么建议？

UPDATE

项目列表:

ls -l
-rw-r--r--  1 snowcrash  snowcrash   77 10 Jul 19:43 bowling.rb
-rw-r--r--  1 snowcrash  snowcrash  205 10 Jul 19:49 bowling_spec.rb

$ rspec bowling_spec.rb 
/Users/snowcrash/.rvm/rubies/ruby-2.0.0-p195/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require': cannot load such file -- bowling (LoadError)

和代码清单:

规格:

# bowling_spec.rb
require 'bowling'

describe Bowling, "#score" do
  it "returns 0 for all gutter game" do
    bowling = Bowling.new
    20.times { bowling.hit(0) }
    bowling.score.should eq(0)
  end
end

班级档案:

# bowling.rb
class Bowling
  def hit(pins)
  end

  def score
    0
  end
end

遗憾的是,rspec主页并未告诉您在项目中初始化rspec的情况.

假设您有一个名为'bowling'的项目文件夹,则在保龄球文件夹内运行

rspec --init

这将创建spec目录和两个文件

spec/spec_helper.rb
.rspec

该.rspec文件允许您定义颜色和格式等首选项

--color
--format documentation

现在spec_helper.rb,添加require "bowling"

# This file was generated by the `rspec --init` command. Conventionally, all
# specs live under a `spec` directory, which RSpec adds to the `$LOAD_PATH`.
# Require this file using `require "spec_helper"` to ensure that it is only
# loaded once.

require "bowling"

# See http://rubydoc.info/gems/rspec-core/RSpec/Core/Configuration
RSpec.configure do |config|
  config.treat_symbols_as_metadata_keys_with_true_values = true
  config.run_all_when_everything_filtered = true
  config.filter_run :focus

  # Run specs in random order to surface order dependencies. If you find an
  # order dependency and want to debug it, you can fix the order by providing
  # the seed, which is printed after each run.
  #     --seed 1234
  config.order = 'random'
end

现在在你的内部bowling_spec.rb,添加`require"spec_helper"

require "spec_helper"

class Bowling
  def hit(pins)
  end

  def score
    0
  end
end

此外,您添加的任何其他规格都需要添加require "spec_helper".spec_helper.rb中的注释解释了为什么这是必要的.

以下是设置和使用rspec的初学者解释

祝好运
