我正在研究 Michael Hartl 的 ruby on rails 教程中关于分页的第 9.3.3 部分，我卡住了：运行 rspec 测试我收到一条错误消息，指出 gem FactoryGirl 有问题。你认为可能是什么问题？

users_pages_spec.rb：

 describe "pagination" do

  before(:all) { 30.times { FactoryGirl.create(:user) } }
  after(:all)  { User.delete_all }

  it { should have_selector('div.pagination') }

  it "should list each user" do
    User.paginate(page: 1).each do |user|
      expect(page).to have_selector('li', text: user.name)
    end
  end
end

factories.rb:

    FactoryGirl.define do
  factory :user do
    sequense(:name)   { |n| "Person #{n}" }
    sequense(:email)  { |n| "person_#{n}@example.com" }
    password "foobar"
    password_confirmation "foobar"
  end
end

【解决方案1】：

我找到了答案！ factory.rb 中的方法“sequence”写错了。现在所有测试都是绿色的。

犯了同样的错误，输入错误的单词trait。错误信息非常无用。
