Question

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：\用户\ Nikita.Harrison \ AutomatedTesting \ cash_withdrawal＆GT;黄瓜无法加载此类文件 - CAPTURE_CASH_AMOUNT（LoadError） C：/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb：55：在 r equire' C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in征服' 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:in load' 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:in load_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"，我会收到此错误：

IRB（主）：006：0＆GT;需要“CAPTURE_CASH_AMOUNT”LoadError：无法加载这样的文件 - CAPTURE_CASH_AMOUNT 来自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:in要求' 来自（irb）：6 来自C：/ Ruby193 / bin / irb：12：在''

我尝试了许多修复程序，包括'require_relative'，似乎没有解决我的问题。如果我从require 'CAPTURE_CASH_AMOUNT'文件中删除cash_withdrawal_steps.rb并运行黄瓜，那么我的“步骤定义”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，我会得到：

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
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需的所有信息。

Answer 1

我刚遇到同样的问题，我认为这是捆绑销商的问题。无论如何，我通过运行来解决了这个问题：

bundle update
bundle exec ruby <yourfilename.rb>

希望这有帮助！

Answer 2

我之前遇到过同样的问题。我通过添加一个简单的

来修复它

require rubygems

在我所有需要的行代码之前。

Answer 3

每当你安装一个新的gem时，你需要更新这个包（正如@zwolfe指出的那样）。因此，运行：

bundle update

您应该能够使用简单的：

运行Ruby脚本

ruby <yourRubyScript.rb> 要么 bundle exec ruby <yourRubyScript.rb

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