これは最も奇妙なことです：

> User.count
   (74.7ms)  SELECT COUNT(*) FROM "users" 
 => 0 
2.0.0p0 :002 > User
 => User(id: integer, email: string, encrypted_password: string, reset_password_token: string, reset_password_sent_at: datetime, remember_created_at: datetime, sign_in_count: integer, current_sign_in_at: datetime, last_sign_in_at: datetime, current_sign_in_ip: string, last_sign_in_ip: string, created_at: datetime, updated_at: datetime, name: string, confirmation_token: string, confirmed_at: datetime, confirmation_sent_at: datetime, unconfirmed_email: string) 
2.0.0p0 :003 > User.create(email: "abc@test.com", password: "test123", password_confirmation: "test123")
   (140.0ms)  BEGIN
  User Exists (543.7ms)  SELECT 1 AS one FROM "users" WHERE "users"."email" = 'abc@test.com' LIMIT 1
   (0.3ms)  ROLLBACK
 => #<User id: nil, email: "abc@test.com", encrypted_password: "$2a$10$s7Ak0w04l3UixRqZbuvrJeLJb/AGD4FxQudSqcvYzDll...", reset_password_token: nil, reset_password_sent_at: nil, remember_created_at: nil, sign_in_count: 0, current_sign_in_at: nil, last_sign_in_at: nil, current_sign_in_ip: nil, last_sign_in_ip: nil, created_at: nil, updated_at: nil, name: nil, confirmation_token: nil, confirmed_at: nil, confirmation_sent_at: nil, unconfirmed_email: nil> 
2.0.0p0 :004 > User.all
  User Load (30.4ms)  SELECT "users".* FROM "users" 
 => [] 
> User.where(:email => "abc@test.com")
  User Load (24.8ms)  SELECT "users".* FROM "users" WHERE "users"."email" = 'abc@test.com'
 => []

何が起こっている？

User.rbDevise と Rolify が付属するのと同じくらいバニラです。

class User < ActiveRecord::Base
  rolify
  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable, :confirmable,
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :role_ids, :as => :admin
  attr_accessible :name, :email, :password, :password_confirmation, :remember_me

  has_one :store
#  has_many :items,

@ whit-kimmeyの提案に従って、私が試した別のこと：

> User.create!({email: "abc@test.com", password: "test123", password_confirmation: "test123"}, without_protection: true)
   (1.3ms)  BEGIN
  User Exists (105.5ms)  SELECT 1 AS one FROM "users" WHERE "users"."email" = 'abc@test.com' LIMIT 1
   (0.3ms)  ROLLBACK
ActiveRecord::RecordInvalid: Validation failed: Password is too short (minimum is 8 characters)

したがって、pw 8 の文字を作成すると、うまくいくように見えますが、これは奇妙です。しかし、それでも、そのメール アドレスを持つユーザーが既に存在するという理由には答えられませんか?

ユーザーがどこかに存在するとは言いません。ユーザーが存在するかどうかを知るために、ActiveRecord によって実行されるクエリを見ているだけです。実際のエラーを取得したい場合は、これを試してください：

> user = User.new(email: "abc@test.com", password: "test123", password_confirmation: "test123")
> user.valid?
> user.errors.full_messages

検証を確認します。おそらく、名前またはその他の属性を検証しています。
