我有一个问题，Rspec加载路由两次并因此抛出错误。 我一直试图弄清楚这几天没有运气。搜索互联网并不会带来太大的影响。当我运行rspec时，它会发出以下错误：
/home/user/.rvm/gems/ruby-2.0.0-p247/gems/actionpack-4.0.1/lib/action_dispatch/routing/route_set.rb:434:in `add_route': Invalid route name, already in use: 'root' (ArgumentError)
You may have defined two routes with the same name using the `:as` option, or you may be overriding a route already defined by a resource with the same naming. For the latter, you can restrict the routes created with `resources` as explained here:

这是我的routes.rb文件：
App::Application.routes.draw do
root 'registrations#new'
end
还有其他内容，但我可以将它们全部评论出来并仍然得到错误。因此它们无关紧要。
spec_helper.rb：
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
#Capybara
require 'capybara/rspec'
Dir[Rails.root.join("spec/support/**/*.rb")].each { |f| require f }
# Checks for pending migrations before tests are run.
# If you are not using ActiveRecord, you can remove this line.
ActiveRecord::Migration.check_pending! if defined?(ActiveRecord::Migration)
RSpec.configure do |config|
config.include Helpers
config.fixture_path = "#{::Rails.root}/spec/fixtures"
config.use_transactional_fixtures = true
config.infer_base_class_for_anonymous_controllers = false
config.order = "random"
end
我的Gemfile的一部分
group :development, :test do
gem 'launchy'
gem 'rspec-rails', '~> 2.0'
gem 'capybara', '~> 2.1.0'
gem 'factory_girl_rails', '~> 4.0'
end
问题是Rspec正试图加载routes.rb两次。我通过将puts "here"放在routes.rb文件中来测试它。为了爱SO，我无法弄清楚为什么，或者如何调试这个。
当我运行rake routes时，它只显示一个root路由，如果我在routes.rb中注释掉它，那么它就不会显示。似乎一切都是正确的，除了rspec不起作用。
此外，这是一个类似的问题When I use rspec: Invalid route name, already in use: 'root' (ArgumentError)，但它不一样（OP不清楚） - 我知道在我的情况下，原因是因为Rspec正在加载两次路由。请帮助，我真的坚持这个。现在任何建议都会很好。
