我正在使用rails 4.2.x和Mongoid。当我尝试在生产模式下运行服务器时，我收到以下错误，但它在开发模式下运行顺利，不知道为什么我收到此错误。我试过预备驴但没有运气。
=> Booting Thin
=> Rails 4.2.1 application starting in production on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server

答案 0 :(得分：1)
错误已经从我使用过的邮件中提升了＃34;包括ActionView :: Helpers＆＃34;在电子邮件课外面。
我通过在类中保留包含ActionView :: Helpers来修复它，我不确定这个包含顺序。我改变了如下
include ActionView::Helpers
class EmailMailer < ActionMailer::Base
到
class EmailMailer < ActionMailer::Base
include ActionView::Helpers
希望它对某人有帮助，我仍在搜索在课程中包含模块的顺序，一旦我找到了我将在此处发布的所需信息。
