我目前使用的是 Ruby 1.9.3 版(尽管我在使用 Ruby 2.0.0 时遇到了同样的问题)。在 Windows 7 64 位上。我正在关注“The Cucumber Book”并卡在第 7.2 章 - “使用转换删除重复项”。我的文件夹结构如下:

\cash_withdrawal
\cash_withdrawal\Gemfile
\cash_withdrawal\Gemfile.lock
\cash_withdrawal\features
\cash_withdrawal\features\cash-withdrawal.feature
\cash_withdrawal\features\step_definitions
\cash_withdrawal\features\step_definitions\cash_withdrawal_steps.rb
\cash_withdrawal\features\step_definitions\lib
\cash_withdrawal\features\step_definitions\lib\nice_bank.rb
\cash_withdrawal\features\support
\cash_withdrawal\features\support\env.rb
\cash_withdrawal\features\support\transforms.rb
\cash_withdrawal\features\support\world_extensions.rb

在我的 cash_withdrawal_steps.rb我有的文件:

require 'CAPTURE_CASH_AMOUNT'

Given /^I have deposited (#{CAPTURE_CASH_AMOUNT}) in my Account$/ do |amount|
  my_account.deposit(amount)
  my_account.balance.should eq(amount), 
    "Expected the balance to be #{amount} but it was #{my_account.balance}"
end

当我运行 cucumber我得到:

C:\Users\Nikita.Harrison\AutomatedTesting\cash_withdrawal>cucumber cannot load such file -- CAPTURE_CASH_AMOUNT (LoadError) C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in r equire' C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in r equire' C:/Users/Nikita.Harrison/AutomatedTesting/cash_withdrawal/features/step_definiti ons/cash_withdrawal_steps.rb:1:in <top (required)>' C:/Ruby193/lib/ruby/gems/1.9.1/gems/cucumber-1.3.10/lib/cucumber/rb_support/rb_l anguage.rb:122:inload' C:/Ruby193/lib/ruby/gems/1.9.1/gems/cucumber-1.3.10/lib/cucumber/rb_support/rb_l anguage.rb:122:in load_code_file' C:/Ruby193/lib/ruby/gems/1.9.1/gems/cucumber-1.3.10/lib/cucumber/runtime/support _code.rb:180:inload_file' C:/Ruby193/lib/ruby/gems/1.9.1/gems/cucumber-1.3.10/lib/cucumber/runtime/support _code.rb:83:in block in load_files!'

如果我运行 irb然后运行 ​​require "CAPTURE_CASH_AMOUNT"我收到此错误:

irb(main):006:0> require "CAPTURE_CASH_AMOUNT" LoadError: cannot load such file -- CAPTURE_CASH_AMOUNT from C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_requir e.rb:55:in require' from C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_requir e.rb:55:inrequire' from (irb):6 from C:/Ruby193/bin/irb:12:in `'

我尝试了很多修复方法，包括“require_relative”，但似乎无法解决我的问题。 如果我删除 require 'CAPTURE_CASH_AMOUNT'来自 cash_withdrawal_steps.rb文件并运行 cucumber 然后我的“步骤定义”没有按定义显示:

C:\Users\Nikita.Harrison\AutomatedTesting\cash_withdrawal>cucumber

 You can implement step definitions for undefined steps with these
 snippets:

 Given(/^I have deposited \$(\d+) in my Account$/) do |arg1|   pending
 \# express the regexp above with the code you wish you had end

如果我添加 require File.join(File.dirname("C:/Users/Nikita.Harrison/AutomatedTesting/cash_withdrawal/features/support"), 'support', 'transforms')到 env.rb文件并运行 cucumber我得到:

 C:/Users/Nikita.Harrison/AutomatedTesting/cash_withdrawal/features/support/trans

我知道我一定是做错了什么，但我就是找不到什么需要帮助。 gem 文件内容:

# This Gemfile lists all Gems used throughout the book - with versions.
source :rubygems

# Build stuff
gem 'bundler', '1.5.3'
#gem 'rake', '10.1.1'
#gem 'watchr', '0.7'
#gem 'bcat', '0.6.2'

# General stuff
#gem 'aruba', '0.4.11'
gem 'cucumber', '1.3.10', :require => 'cucumber'
gem 'rake', '10.1.1'
gem 'rspec', '2.14.1', :require => 'cucumber'
gem 'rspec-expectations', '2.14.5'
gem 'watir-webdriver', '0.6.7'

我想我已经包含了所有需要的信息。

最佳答案

我刚刚遇到了同样的问题，我相信这是 bundler 的问题。无论如何，我通过运行解决了这个问题:

bundle update
bundle exec ruby <yourfilename.rb>

希望这对您有所帮助!
