我正在尝试使用capistrano部署Ruby on Rails应用程序，但是在运行之后：
cap production deploy:initial
部署失败并显示下一个错误：

Devise宝石似乎是错误的，但是我已经尝试修复了几个小时，而且我的想法已经用完了。
rails应用程序在本地运行没有问题。

您好，您可以在Production / Stage Environment中本地运行Rails应用程序。
rails s RAILS_ENV=production
rails server -e production
检查一切是否正常
答案 1 :(得分：0)
希望我的问题对将来的某个人有用。问题是，显然模型需要从Device::Models扩展，我在Devise文档中没有找到任何内容，但是在将extend Devise::Models添加到我的Client模型中之后，该错误不再显示了。 / p>
class Client < ActiveRecord::Base
extend Devise::Models
# All my methods here
end
如果有人知道为什么会发生这种情况，那么您可以评论一下原因。
