我正在通过Ruby on Rails 2nd Ed。，Hartl工作。在3.3.3节中，我用一些嵌入式Ruby删除了一些静态文本后，我的测试失败了。测试通过以前没有问题。Ruby on Rails嵌入式红宝石生成错误

rspec的

require 'spec_helper' 

    describe "Home pages" do 

     describe "Home page" do 
     it "should have the h1 'Sample App'" do 
      visit '/static_pages/home' 
      page.should have_selector('h1', :text => 'Sample App') 
     end 

     it "should have the title 'Home'" do 
      visit '/static_pages/home' 
      page.should have_selector('title', :text => "Ruby on Rails Tutorial Sample     App | Home") 
     end 
     end 
    end

home.html.erb

<% provide (:title, 'Home') %> 
    <!DOCTYPE html>

我认为你需要删除空白在t之前他圆括号

provide (:title, 'Home')

应该

provide(:title, 'Home')

它现在的工作。这是空白。谢谢。我知道它必须是简单的东西，就是看不到它。好工作muttonlamb！ – JanuskaE

就像未来的FYI一样，Ruby可以对括号做些挑剔。忽略括号（显然）时可以留空白，但如果将它放在方法调用和括号之间，有时会产生混淆。尽管这并不适用，但最好保持一致，并确保在括号之前不留空格 – muttonlamb
