无法在Rails上安装devise gem＆＃34; unidentified方法进行安装＆＃34;

标签： ruby-on-rails ruby ruby-on-rails-3 devise

当我尝试执行＆＃34; rails generate devise：install＆＃34;我收到此错误消息：

我已多次尝试重新安装设计gem。当我尝试启动服务器时，也会出现此错误。我想知道这个原因是不是最初尝试使用＆＃34; rails generate devise install＆＃34;来安装设计宝石。而不是在设计和安装之间放置冒号。

看起来您的意外安装创建了安装模型和其他文件。或许删除那些？

我正在使用设备gem并且没有设计安装。然后使用，cmd rails g device auth在这种情况下rails抛出错误比使用这个方法我的问题解决了

extend Devise::Models

in my auth.rb files

class Auth < ApplicationRecord  
   extend Devise::Models  
end
