Ruby on rails Rails rspec意外tIDENTIFIER

我正在阅读RoR教程，遇到了以下错误，似乎无法理解。我完全复制了示例代码，但我的rspec测试仍然无法运行，控制台甚至无法创建新用户

谢谢你的帮助，谢谢

错误：

以下是我的rspec测试： 需要“spec\u helper”

describe User do

  before { @user = User.new(name: "Example User", email: "user@example.com") }

  subject { @user }

  it { should respond_to(:name) }
  it { should respond_to(:email) }

  it { should be_valid }

  describe "when name is not present" do
    before { @user.name = " " }
    it { should_not be_valid }
  end

  describe "when name is too long" do
    before { @user.name = "a"* 51 }
    it { should_not be_valid }
  end

  describe "when email format is not valid" do
    it "should be invalid" do
      addresses = %w[user@foo,com user_at_foo.org example.user@foo. 
                    foo@bar_baz.com foo@bar+baz.com]
      addresses.each do |invalid_address|
        @user.email = invalid_address
        @user.should_not be_valid
      end
    end
  end

  describe "when email format is valid" do
    it "should be valid" do
      addresses = %w[user@foo.com A_US-ER@f.b.org first.last@foo.jp a+b@baz.cn]
      addresses.each do |valid_address|
        @user.email = valid_address|
        @user.should be_valid
      end
    end
  end

  describe "when email address is already taken" do
    before do
      user_with_same_email = @user.dup
      user_with_same_email.email = @user.email.upcase
      user_with_same_email.save
    end

    it { should_not be_valid }
  end
end

这是我的用户模型：

class User < ActiveRecord::Base
  attr_accessible :name, :email, :password, :password_confirmation
  has_secure_password

  before_save { |user| user.email = email.downcase }

  validates :name, presence: true, length: { maximum: 50 }
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence:   true,
                    format:     { with: VALID_EMAIL_REGEX },
                    uniqueness: { case_sensitive: false }
  validates :password, presence: true, length: { minimum: 6 }
  validates :password_confirmation, presence: true
end

这行有一个输入错误：

    @user.email = valid_address|

有一个不应该在那里的尾随
