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

如果我运行irb然后运行require "CAPTURE_CASH_AMOUNT"，我会收到此错误：

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：

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'

我想我已经包含了所需的所有信息。

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！

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。
答案 2 :(得分：0)
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
