我已经阅读了该站点上的许多问题以及 ExceptionNotifier 的 GitHub 文档及其在 Rails 3 中的实现，但我不明白为什么它在我的生产服务器上对我不起作用。在我的本地机器（Mac）上，它可以在生产环境中完美运行。但是在我使用 capistrano 部署并在 Linux 机器上使用 unicorn 运行应用程序后，我的 unicorn 日志抱怨uninitialized constant ExceptionNotifier我的环境/production.rb 文件中有一个，即使我的本地机器似乎认为它很好。我已经尝试过这两种实现： gem 'exception_notification', :require => 'exception_notifier'和 gem 'exception_notification_rails3', :require => 'exception_notifier'. 两者都抛出此错误。这是我的生产.rb

Rl4::Application.configure do
  # code omitted
  # Enable ExceptionNotifier, having it ignore its default exceptions
  config.middleware.use ExceptionNotifier,
    sender_address: 'reports@ctatechs.com',
    exception_recipients: 'brice@ctatechs.com',
    ignore_exceptions: ExceptionNotifier.default_ignore_exceptions
end

这是我的 Gemfile

source 'https://rubygems.org'
# lots omitted
gem 'exception_notification_rails3', :require => 'exception_notifier'
# lots more omitted

这是我的 application_controller.rb，它实现了 gem：

class ApplicationController < ActionController::Base
  protect_from_forgery

  # By default, only production ENV considers requests not local
  unless Rails.application.config.consider_all_requests_local
    rescue_from Exception, :with => :server_error
    rescue_from ActionController::UnknownAction, :with => :not_found
    rescue_from ActionController::UnknownController, :with => :not_found
    rescue_from ActionView::MissingTemplate, :with => :not_found
  end

  private
    def server_error(exception)
      ExceptionNotifier::Notifier.exception_notification(request.env, exception).deliver
      respond_to do |format|
        format.html { render template: '/500.html', layout: 'application/layout', status: 500 }
        format.all { render nothing: true, status: 500 }
      end
    end

    def not_found(exception)
      ExceptionNotifier::Notifier.exception_notification(request.env, exception).deliver
      respond_to do |format|
        format.html { render template: '/404.html', layout: 'application/layout', status: 404 }
        format.all { render nothing: true, status: 404 }
      end
    end
end

同样，目前实施不是我的问题。不知何故，gem 未正确安装或未正确初始化。我确实在 Linux 机器上为 gem 的两个版本以及“exception_notifier”运行了 sudo gem install。没有骰子。想法？

附加信息 我刚刚尝试将 gem 重新安装为插件，并在更改 production.rb 文件以使用后得到相同的错误config.middleware.use ::ExceptionNotifier。但是，这些修改仍然适用于我的本地计算机。也许我错过了 Linux 机器上的另一个软件？文档上似乎没有提到任何内容...

请求 gem 版本

我正在使用 exception_notification，v. 3.0.1

说我对这个问题的解决是如此微不足道，我感到很惭愧。

$ cap unicorn:stop
$ cap unicorn:start

我在部署过程中的重新启动任务从未真正停止服务器实例，因此没有加载新库，因此没有加载异常。

女士们，先生们，不要忘记尝试将其关闭并重新打开。曾经。感谢所有帮助我解决这个问题的人。

这是您可以解决的方法。

考虑到您的 development 和 production.rb 中已经有 SMTP 设置

宝石文件 

gem 'exception_notification' ,'3.0.0', :require => 'exception_notifier'

应用程序.rb

config.middleware.use ExceptionNotifier,
  :email_prefix => "[ERROR]",
  :sender_address => %{"Exception Notifier" <XYZ@gmail.com>},
  :exception_recipients => %w{ABC@gmail.com}

application_controller.rb

#render 500 error 
def render_error(exception)
  ExceptionNotifier::Notifier.exception_notification(request.env, exception).deliver
  respond_to do |f| 
    ...
  end
end

对我来说，它适用于开发和生产（Heroku）。

希望它也能帮助你。
干杯：）
