我不确定它是否因为设计

这是我的路线文件

Wishlistize::Application.routes.draw do
  devise_for :users
end

和environment.rb

# Load the Rails application.
require File.expand_path('../application', __FILE__)

# Initialize the Rails application.
Wishlistize::Application.initialize!

当我运行rake db：migrate时，我得到了这个用户模型：

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

好的，我想通了。根据我读过的教程，我实际上并没有rails g devise:install，而是直接rails g devise:user。这似乎导致了这个问题。我安装了边缘版本，很明显。

安装设备后在rails中获取错误
