水豚rspec更深入的测井？

在执行click_按钮后的某个时刻，我正在检索无法转储的singleton错误。rspec的所有输出告诉我：

1) home not logged in sign in should contain content with 'Add new charity
 Failure/Error: click_button "Install"
 TypeError:
   singleton can't be dumped
 # (eval):2:in `click_button'
 # ./spec/integration/home_spec.rb:29:in `block (4 levels) in <top (required)>'

spec_helper.rb：

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'capybara/rails' 
require 'capybara/dsl'
require "rack_session_access/capybara"

# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

Rails.application.config do
  config.middleware.use RackSessionAccess::Middleware
end

RSpec.configure do |config|
  # == Mock Framework

  # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:

  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
  config.fixture_path = "#{::Rails.root}/spec/factories"

  # If you're not using ActiveRecord, or you'd prefer not to run each of your
  # examples within a transaction, remove the following line or assign false
  # instead of true.
  config.use_transactional_fixtures = true

  # If true, the base class of anonymous controllers will be inferred
  # automatically. This will be the default behavior in future versions of
  # rspec-rails.
  config.infer_base_class_for_anonymous_controllers = false

  # RSpec automatically cleans stuff out of backtraces;
  # sometimes this is annoying when trying to debug something e.g. a gem
  config.backtrace_clean_patterns = [
    /\/lib\d*\/ruby\//,
    /bin\//,
    /gems/,
    /spec\/spec_helper\.rb/,
    /lib\/rspec\/(core|expectations|matchers|mocks)/
  ]

您是否考虑过使用类似Pry的工具来简化此过程？它与您的家庭规范中包含的一个文件有关

在这里您可以找到Pry：

然后，您可以在代码中插入binding.pry，您应该能够进入执行环境并检查类似irb的会话中发生了什么

---

否则，您需要发布您的主页_spec.rb，以便我们可以开始理论化。

我确实安装了pry。我尝试一下，看看这是否能让我对正在发生的事情有更深入的了解。为了以防万一，我为spec文件和spec助手添加了代码。谢谢
