我正在编写第 8 章的 RoR 教程。我正在尝试完成第 8.2.4 节 - 更改布局链接并运行$ bundle exec rspec spec/，但出现以下错误：

Failures:

     Failure/Error: click_button "Sign in"

Failed examples:

rspec ./spec/requests/authentication_pages_spec.rb:38 # Authentication signin with valid information 
rspec ./spec/requests/authentication_pages_spec.rb:41 # Authentication signin with valid information

根据输出，我检查了spec/requests/authentication_pages_spec.rb，但似乎找不到错误。这就是我所拥有的：

require 'spec_helper'

describe "Authentication" do

subject { page }

describe "signin page" do 
    before { visit signin_path } 

    it { should have_selector('h1',    text: 'Sign in') }
    it { should have_selector('title', text: 'Sign in') }
end

  describe "signin" do
before { visit signin_path }

describe "with invalid information" do
        before { click_button "Sign in" }

        it { should have_selector('title', text: 'Sign in') }
        it { should have_selector('div.alert.alert-error', text: 'Invalid') }

    describe "after visiting antoher page" do 
        before { click_link "Home" }
        it { should_not have_selector('div.alert.alert-error') } 
    end
end

    describe "with valid information" do 
        let(:user) { FactoryGirl.create(:user) }
        before do
            fill_in "Email",    with: user.email
            fill_in "Password", with: user.password
            click_button "Sign in"
        end

        it { should have_selector('title', text: user.name) }
        it { should have_link('Profile', href: user_path(user)) }
        it { should have_link('Sign out', href: signout_path) }
        it { should_not have_link('Sign in', href: signin_path) }
    end
end
end

我似乎找不到错误。根据错误输出，我应该在哪里查看任何建议？谢谢你。

检查您的 config/routes.rb 文件以确保：

match '/signin', to: 'sessions#new'

与您的会话控制器所看到的相匹配。“sessions_controller.rb”的创建方法应该有：

def create
  user = User.find_by_email(params[:session][:email].downcase)
  if user && user.authenticate(params[:session][:password])
    sign_in user
    redirect_back_or user
  else
    flash.now[:error] = 'Invalid email/password combination'
    render 'new'
  end
end

只是我的猜测。在本教程中，我目前也在该区域附近。祝你好运，我希望这会有所帮助！

可能有点晚了，但无论如何......

检查 app/controllers/application_controller.rb 中是否有“include SessionsHelper”

助手默认包含在视图中，但您必须明确地将它们包含在控制器中
