kernel_require.rb：55：在`require'：无法加载此类文件错误

我目前正在使用Ruby版本1.9.3（尽管我在Ruby 2.0.0中遇到了同样的问题） . 在Windows 7 64位上 . 我正在关注'The Cucumber Book'并且陷入第7.2章 - “删除重复变换” . 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 文件中，我有：

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 时，我得到：

C：\ Users \ Nikita.Harrison \ AutomatedTesting \ cash_withdrawal> cucumber无法加载此类文件 - 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 e 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：在load_files的块中！' C：/Ruby193/lib/ruby/gems/1.9.1/gems/cucumber-1.3.10/lib/cucumber/runtime/support _code.rb:82:ineach'C:/Ruby193/lib/ruby/gems/1.9 .1 / gems / cucumber-1.3.10 / lib / cucumber / runtime / support _code.rb:82:in load_files！' C：/Ruby193/lib/ruby/gems/1.9.1/gems/cucumber-1.3.10/lib/cucumber/runtime.rb:184:inload_step_definitions'C:/Ruby193/lib/ruby/gems/1.9.1/ gems / cucumber-1.3.10 / lib / cucumber / runtime.rb:42:in run！' C：/Ruby193/lib/ruby/gems/1.9.1/gems/cucumber-1.3.10/lib/cucumber/cli/main.rb:47:nacecute！' C：/Ruby193/lib/ruby/gems/1.9.1/gems/cucumber-1.3.10/bin/cucumber:13:in <top（re quired）>'C：/ Ruby193 / bin / cucumber：23：inload 'C：/ Ruby193 / bin / cucumber：23：in''

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：无法加载此类文件 - 来自C的CAPTURE_CASH_AMOUNT：/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：在''

我've tried many fixes including ' require_relative'似乎没有解决我的问题 . 如果我从 cash_withdrawal_steps.rb 文件中删除 require 'CAPTURE_CASH_AMOUNT' 并运行黄瓜，那么我的'Step Definition'不会按照定义显示：

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

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

我知道我必须在这里做错事，但我找不到什么，需要帮助 . Gemfile内容：

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

# Build stuff
