Devise 令牌身份验证错误：未设置 Devise.secret_key

我目前正在使用 Devise 令牌身份验证 (https://github.com/lynndylanhurley/devise_token_auth https://github.com/lynndylanhurley/devise_token_auth) gem 并使其在开发中运行良好。但是，在我的生产环境中，当我运行时rake db:migrate，我收到以下错误：

rake aborted!
Devise.secret_key was not set. Please add the following to your Devise initializer:

  config.secret_key = 'my secret key'

Please ensure you restarted your application after installing Devise or setting the key.

当我添加密钥时，如错误消息所示，出现以下错误：

rake aborted!
NoMethodError: undefined method `secret_key=' for DeviseTokenAuth:Module

我尝试过以下方法 - 重新安装宝石 - 设置检查以查看 Devise 配置文件中是否有 Rails.env==“生产” - 更新了宝石 - 使用生成器重新安装设备 - 删除表并使用生成器创建的新迁移进行重新迁移

这是我按照要求输入密钥时的initializers/devise_auth.rb 文件：

DeviseTokenAuth.setup do |config|
  # By default the authorization headers will change after each request. The
  # client is responsible for keeping track of the changing tokens. Change
  # this to false to prevent the Authorization header from changing after
  # each request.
  #config.change_headers_on_each_request = true

  # By default, users will need to re-authenticate after 2 weeks. This setting
  # determines how long tokens will remain valid after they are issued.
  #config.token_lifespan = 2.weeks

  config.secret_key = 'my secret key'

  # Sometimes it's necessary to make several requests to the API at the same
  # time. In this case, each request in the batch will need to share the same
  # auth token. This setting determines how far apart the requests can be while
  # still using the same auth token.
  #config.batch_request_buffer_throttle = 5.seconds

  # This route will be the prefix for all oauth2 redirect callbacks. For
  # example, using the default '/omniauth', the github oauth2 provider will
  # redirect successful authentications to '/omniauth/github/callback'
  # config.omniauth_prefix = "/omniauth"
end

任何想法如何解决这一问题？为什么这种情况只发生在生产中？

根据文档，您需要添加config.secret_key = 'my secret key' to

config/initializers/devise_token_auth.rb

FWIW，您可能不想在代码中保存秘密。使用

config.secret_key = ENV[ 'DEVISE_TOKEN_AUTH_SECRET_KEY' ]

编辑：我认为问题是你需要设置Devise.secret_key，而不是 Devise Token Auth 密钥。有 Devise 初始化程序吗？
