リスト 7.29 のこのコードが必要です。ガアバターの編集用です。

リスト7.29。gravatar_for ヘルパーのオプションの :size パラメーターを定義します。

アプリ/ヘルパー/users_helper.rb

module UsersHelper

  # Returns the Gravatar (http://gravatar.com/) for the given user.
  def gravatar_for(user, options = { size: 50 })
    gravatar_id = Digest::MD5::hexdigest(user.email.downcase)
    size = options[:size]
    gravatar_url = "https://secure.gravatar.com/avatar/#{gravatar_id}?s=#{size}"
    image_tag(gravatar_url, alt: user.name, class: "gravatar")

user_pages 仕様に一致しないこれらの行があります

describe "index" do
    before do
      sign_in FactoryGirl.create(:user)
      FactoryGirl.create(:user, name: "Bob", email: "bob@example.com")
      FactoryGirl.create(:user, name: "Ben", email: "ben@example.com")
