让 spork 与 Ruby 1.9.2/3 + Rails 3.1 + Rspec 一起工作？

Question

那里有很多可靠的教程，而且我过去没有遇到太多麻烦。但是，经过几个小时的尝试，我一定错过了一些东西。

我已经完成了标准安装说明，并启动了 spork 服务器：

Using RSpec
Preloading Rails environment
Loading Spork.prefork block...
Spork is ready and listening on 8989!

看起来不错。

然后，我跳到一个新标签并运行我的规范：

$ rspec spec

此命令仅运行一瞬间后不返回任何内容。所以我跳回 spork 服务器查看发生了什么并得到：

Using RSpec
Preloading Rails environment
Loading Spork.prefork block...
Spork is ready and listening on 8989!
Running tests with args ["--color", "spec"]...
Exception encountered: #<DRb::DRbConnError: druby://localhost:56736 - #<Errno::ECONNREFUSED: Connection refused - connect(2)>>

Done.

由于某种原因，drb 连接失败？我疯狂地用谷歌搜索，但似乎没有任何帮助。

一些可能的线索

• 每次我尝试运行套件时，端口（在本例中为 56736）都会发生变化
• 我在 ruby​​ 1.9.2 和 ruby​​ 1.9.3 上得到相同的结果
• 我使用的是 mac（雪豹）并且防火墙已禁用
• 我已经在完全不同的 mac（也是雪豹）上进行了尝试，结果相同。
• 我正在使用最新版本的 cucumber、rspec 和 spork。
• 我也设置了黄瓜叉，但同样失败了。

如您所见，我一直在努力解决这个问题。我的项目使用了很多 gem，而没有 spork 会使测试变得非常非常糟糕。请帮忙...

更新

这是我的spec_helper：

require 'spork'

Spork.prefork do
  ENV["RAILS_ENV"] ||= 'test'
  require File.expand_path("../../config/environment", __FILE__)
  require 'rspec/rails'
  require "email_spec"
  require 'webmock/rspec'
  require 'vcr'
  require 'database_cleaner'

  include Devise::TestHelpers
  include EmailSpec::Helpers
  include EmailSpec::Matchers

  # Stub all updates to search indexes
  class Profile
    def update_tank_indexes ; end
    def delete_tank_indexes ; end
  end
  class Journal
    def update_tank_indexes ; end
  end

  # Apparently rspec doesn't understand <tt>main_app</tt> so stub it out.
  def main_app ; self ; end


  # 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}

  RSpec.configure do |config|

    config.mock_with :rspec

    # 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
    config.extend VCR::RSpec::Macros

    # Always clean the database after running describe/context blocks to ensure a
    # consistent state. This is especially important when using the <tt>rspec-set</tt>
    # method. This method creates setup object once -- and only once -- proir to
    # running an entire describe/context block. In this way, it's similar to using
    # <tt>before(:all)</tt> except that <tt>set</tt> is better because:
    #
    #   * It automatically reloads the object before each example, making it much
    #     safer than before(:all) which can cause bugs if you're not careful.
    #   * It's lazily evaluated.

    DatabaseCleaner.strategy = :truncation
    config.before(:all) do
      DatabaseCleaner.clean
    end
    config.after(:suite) do
      DatabaseCleaner.clean
    end
  end

end

Spork.each_run do
  # This code will be run each time you run your specs.
end

我为此问题开了一张票，但在过去 3.5 个月内没有任何结果：https://github.com/sporkrb/spork/issues/133

更新：我找到了解决方案，并向那张票报告了一切。 tl;dr：将“always_validate_ssl_certifitcates”的 Gemfile 条目更改为包含 :require => false。

你能回滚到 spork 0.8.5 看看它是否有效吗？我刚刚验证了它的工作原理。
