按照升级到 rails 4 的 railscasts 完成该过程，这样做，我破坏了我的用户测试套件。

user_spec.rb ：

describe User do

    before do
        @user = User.new(email: "user@example.com",
                   password: "foobar", password_confirmation: "foobar")
    end

    subject(@user)

    it { should respond_to(:email)}
    it { should respond_to(:password_digest)}
    it { should respond_to(:password)}
    it { should respond_to(:password_confirmation)}
    it { should respond_to(:authenticate)}
end

这是 rspec 吐出的内容：

bundle exec rspec spec/models/user_spec.rb
/.rvm/gems/ruby-2.0.0-p247/gems/rspec-core-2.13.1/lib/rspec/core/memoized_helpers.rb:180:in
`define_method': tried to create Proc object without a block (ArgumentError)

这是我的宝石文件

source 'https://rubygems.org'
ruby '2.0.0'

gem 'rails', '4.0.0'
gem 'bootstrap-sass', '2.3.2.0'
gem 'will_paginate'
gem 'bootstrap-will_paginate'
gem 'bcrypt-ruby', '3.0.1'

group :development, :test do
  gem 'sqlite3', '1.3.7'
  gem 'rspec-rails', '2.13.1'
end

# Gems used only for assets and not required
# in production environments by default.
gem 'sass-rails', '4.0.0'
gem 'uglifier', '2.1.1'
gem 'coffee-rails', '4.0.0'
gem 'jquery-rails', '2.2.1'
gem 'turbolinks', '1.1.1'
gem 'jbuilder', '1.0.2'

group :test do
  gem 'selenium-webdriver', '2.35.1'
  gem 'capybara', '2.1.0'
  gem 'factory_girl_rails'
end

group :production do
  gem 'pg', '0.15.1'
  gem 'rails_12factor', '0.0.2'
end

是什么导致自己出现这些问题？谢谢！

更新：用户.rb：

class User < ActiveRecord::Base
  before_save {self.email = email.downcase}
  VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, presence: true, format: { with: VALID_EMAIL_REGEX },
        uniqueness: { case_sensitivity: false }

  has_secure_password
  validates :password, length: { minimum: 6 }   
end

subject将块作为参数。你需要说subject {@user}。]

你得到了你得到的错误，因为 Ruby 试图将@user其视为一个Proc对象。
