Ruby 1.8.7上的Rspec故障

我正在使用brew安裝和rvm在mac osx10.8上安裝Ruby 1.8.7。當我做bundle exec spec spec/requests/static_pages_spec.rb我得到這些錯誤

FFFFF.FFF

有誰知道如何解決任何/所有這些錯誤的？ 這裏是我的相關文件： 的routes.rb

SampleApp::Application.routes.draw do 

    match '/static_pages/home', :to =>'static_pages#home' 
    match '/help' => 'static_pages#help', :via => 'get' 
    match '/about' => 'static_pages#about', :via => 'get' 
    match '/contact' => 'static_pages#contact', :via => 'get' 

    get "static_pages/home" 

    get "static_pages/help" 

    get "static_pages/about" 

    get "static_pages/contact" 

static_pages_spec.rb

require 'spec_helper'

    describe "Home page" do

我已經更新了我的Xcode，libiconv的，以及相關的一切。我目前大部分是通過ruby on rails教程第5章的方式，而我對於我的生活不知道是什麼導致了這些錯誤。我也跟着教程完美到目前爲止與少數例外，如改變冒號方法爲哈希火箭和不同的寶石版本等

Answer 1

當您創建使用match和get這樣的路線，默認情況下，您不會獲得像help_path這樣的命名路線。運行rake routes以查看哪些路由已配置，以及他們的命名助手（如果有）是什麼。您可能沒有多個命名路線。

您可以使用:as命名您的路線：

match '/help' => 'static_pages#help', :via => 'get', :as => 'help' 

，將讓你help_path和help_url。如果您使用例如resources :help，很多魔法都是爲你完成的。在通往靜態資產的路線中，使用:as是最佳方法。
