kernel_require.rb：55：在`require'：无法加载这样的文件错误 [英] kernel_require.rb:55:in `require': cannot load such file error

问题描述

我目前使用的是Ruby版本1.9.3（虽然我得到了与Ruby 2.0.0相同的问题）。在Windows 7 64位上。我正在关注黄瓜书，被困在第7.2节使用转换删除重复。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_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 档案我有：

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 get：

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

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

我尝试过许多修复，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'，然后运行cucumber，定义未按定义显示：

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:

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

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 我获得：

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:

I知道我必须在这里做错事，但我只是不能找出什么，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

p>我刚遇到同样的问题，我相信这是一个问题与bundler。在任何情况下，我解决这个问题，通过运行：

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>

希望这有助于！
