kernel_require.rb:55:in `require': 无法加载此类文件错误 [英] kernel_require.rb:55:in `require': cannot load such file error

问题描述

我目前使用的是 Ruby 1.9.3 版(尽管我遇到了与 Ruby 2.0.0 相同的问题).在 Windows 7 64 位上.我正在关注The Cucumber Book"并被困在第 7.2 章 - 使用变换删除重复".我的文件夹结构如下:

I'm using Ruby version 1.9.3 at the moment (although I get the same issue with Ruby 2.0.0). On Windows 7 64-bit. I'm following 'The Cucumber Book' and got stuck at the chapter 7.2 - "Removing Duplication with Transforms". My folder structure is as follows:

cash_withdrawal
cash_withdrawalGemfile
cash_withdrawalGemfile.lock
cash_withdrawalfeatures
cash_withdrawalfeaturescash-withdrawal.feature
cash_withdrawalfeaturesstep_definitions
cash_withdrawalfeaturesstep_definitionscash_withdrawal_steps.rb

cash_withdrawalfeaturesstep_definitionslib
ice_bank.rb
cash_withdrawalfeaturessupport
cash_withdrawalfeaturessupportenv.rb
cash_withdrawalfeaturessupport	ransforms.rb
cash_withdrawalfeaturessupportworld_extensions.rb

在我的 cash_withdrawal_steps.rb 文件中，我有:

In my cash_withdrawal_steps.rb file I have:

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:

如果我运行 irb 然后运行 ​​require "CAPTURE_CASH_AMOUNT" 我得到这个错误:

And if I run irb then run require "CAPTURE_CASH_AMOUNT" I get this error:

我尝试了许多修复方法，包括require_relative"，但似乎没有任何方法可以解决我的问题.如果我从 cash_withdrawal_steps.rb 文件中删除 require 'CAPTURE_CASH_AMOUNT' 并运行 cucumber，那么我的步骤定义"不会按定义显示:

I've tried many fixes including 'require_relative' and nothing seems to solve my problem. If I remove require 'CAPTURE_CASH_AMOUNT' from the cash_withdrawal_steps.rb file and run cucumber then my 'Step Definition' doesn't show as defined:

 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:

If I add require File.join(File.dirname("C:/Users/Nikita.Harrison/AutomatedTesting/cash_withdrawal/features/support"), 'support', 'transforms') to the env.rb file and run cucumber I get:

我知道我在这里一定做错了什么，但我就是不知道是什么，需要帮助.Gemfile 内容:

I know I must be doing something wrong here but I just can't find out what and need help. Gemfile contents:

# 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.

I think I've included all the information that is needed.

推荐答案

我刚遇到同样的问题，相信是bundler的问题.无论如何，我通过运行解决了这个问题:

I just encountered the same issue, and I believe it's a problem with bundler. In any case, I solved the problem by running:

bundle update
bundle exec ruby <yourfilename.rb>

希望这会有所帮助！
