那里有很多可靠的教程，过去我没有遇到太多麻烦。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，我跳到一个新选项卡并运行我的规范：
$ rspec spec
此命令仅在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)>>

由于某种原因，drb无法连接？我疯狂地用谷歌搜索，但那里似乎没有任何帮助。
一些可能的线索
56736每次我尝试运行套件时，端口（在这种情况下）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
- 我正在使用 mac（雪豹）并且防火墙被禁用
- 我已经在完全不同的 mac（也是雪豹）上尝试过，结果相同。
- 我正在使用最新版本的黄瓜、rspec 和 spork。
- 我还设置了黄瓜叉，它以同样的方式失败了。
如您所见，我一直在努力解决它一段时间。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.
