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我得到：

C：\ Users \ Nikita.Harrison \ AutomatedTesting \ cash_withdrawal>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:in r equire' C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_require.rb:55:in获取’C：/Users/Nikita.Harrison/AutomatedTesting/cash_withdrawal/features/step_definiti ons / cash_withdrawal_steps.rb：1：in ' C:/Ruby193/lib/ruby/gems/1.9.1/gems/cucumber-1.3.10/lib/cucumber/rb_support/rb_l anguage.rb:122:in加载’C：/Ruby193/lib/ruby/gems/1.9.1/gems/cucumber-1.3.10/lib/cucumber/rb_support/rb_l anguage.rb：122：在load_code_file' C:/Ruby193/lib/ruby/gems/1.9.1/gems/cucumber-1.3.10/lib/cucumber/runtime/support _code.rb:180:in :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：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:in （irb）：6 from C：/ Ruby193 / bin / irb：12：在”

我尝试了许多修复，包括’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 Feature: Cash withdrawal @test Scenario: Successful withdrawal from an account in credit # features\cash_with drawal.feature:4 Given I have deposited $100 in my Account # features\cash_with drawal.feature:5 When I withdraw $20 # features/step_defi nitions/cash_withdrawal_steps.rb:7 Then $20 should be dispensed # features/step_defi nitions/cash_withdrawal_steps.rb:11 And the balance of my account should be $80 # features/step_defi nitions/cash_withdrawal_steps.rb:15 1 scenario (1 undefined) 4 steps (3 skipped, 1 undefined) 0m0.006s You can implement step definitions for undefined steps with these snippets: Given(/^I have deposited \$(\d+) in my Account$/) 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 forms.rb:1: warning: already initialized constant CAPTURE_CASH_AMOUNT Feature: Cash withdrawal @test Scenario: Successful withdrawal from an account in credit # features\cash_with drawal.feature:4 Given I have deposited $100 in my Account # features\cash_with drawal.feature:5 When I withdraw $20 # features/step_defi nitions/cash_withdrawal_steps.rb:7 Then $20 should be dispensed # features/step_defi nitions/cash_withdrawal_steps.rb:11 And the balance of my account should be $80 # features/step_defi nitions/cash_withdrawal_steps.rb:15 1 scenario (1 undefined) 4 steps (3 skipped, 1 undefined) 0m0.013s You can implement step definitions for undefined steps with these snippets: Given(/^I have deposited \$(\d+) in my Account$/) do |arg1| pending \# express the regexp above with the code you wish you had end 

我知道我必须在这里做错事但我无法找到什么并需要帮助。 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，我认为这是捆绑器的问题。 无论如何，我通过运行来解决问题：

 bundle update bundle exec ruby  

希望这可以帮助！

Answer 2

我以前遇到过同样的问题。 我通过添加一个简单的修复它

 require rubygems 

在我所有需要行代码之前。

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

您应该能够简单地使用以下命令运行Ruby脚本：

ruby 或bundle exec ruby
