Ruby on rails RubyonRails教程第9章失败/错误

做过这个练习的人能帮我吗

这是我第一次使用这种编程语言，对这一点没什么影响，但我需要很好地完成，直到第10章是最终评估

如果代码的格式如下所示：

describe "edit" do
   let(:user) { FactoryGirl.create(:user) }
before do
  sign_in user
  visit edit_user_path(user)

describe "page" do
  it { should have_content("Update your profile") }
  it { should have_title("Edit user") }
  it { should have_link('change', href: 'http://gravatar.com/emails') }
end

我可以看出它可能在没有阅读任何代码的情况下被破坏了

所有代码块都正确关闭了吗？看起来不是这样

除了phoet指出的未关闭的块，这些块会导致“undefined method Descripte”错误，在

/app/views/users/index.html.erb

第5行中还会出现错误。错误是nil:NilClass的

未定义方法'each'，这意味着在执行
变量的那一行上有一个变量。每个
都有，但您要么没有设置该变量，要么在设置它时，它被设置为
nil

一般来说，要成功地解决这个问题的方法是阅读错误消息并尝试修复他们的抱怨。如果您单独搜索每个错误消息，您将发现有关特定问题的堆栈溢出问题，这些问题将对您有所帮助
 如果您不提供任何代码，也不指定如何运行代码，我们将无法帮助您修复代码。我标记错误属于两类用户页面，您似乎已发布，但未提供有关您对其所做操作或如何运行代码的任何详细信息。是的，谢谢您，我解决了问题，我描述了一个糟糕的问题，我完全修改并运行
describe "edit" do
   let(:user) { FactoryGirl.create(:user) }
before do
  sign_in user
  visit edit_user_path(user)

describe "page" do
  it { should have_content("Update your profile") }
  it { should have_title("Edit user") }
  it { should have_link('change', href: 'http://gravatar.com/emails') }
end
