未初始化的常量Sidekiq :: Worker（NameError）

Question

今天我发现了sidekiq-mailer，这是一个与Sidekiq集成的精彩宝石，真的可以帮助我的项目。但我在安装/配置方面遇到一些问题，有人可以帮助我吗？我已经看到了所有相关的问题而没有解决我的问题。

宝石文件

目前我使用最新版本的Sidekiq和最新版本的SidekiqMailer。您可以查看我的gemfile：

gem 'sidekiq'
gem "sidekiq-cron" 
gem 'sidekiq-failures' 
gem 'sidekiq_mailer', git: 'https://github.com/andersondias/sidekiq_mailer.git'

我使用所有这些宝石，但用途不同。

文件

目前我有两名工人：一名使用＆＃34; sidekiq＆＃34; +＆＃34; sidekiq-cron＆＃34;和另一个（我认为你有一个很好的猜测）使用＆＃34; sidekiq＆＃34; +＆＃34; sidekiq_mailer＆＃34;。

我有一个 PersonMailer ，但是这并没有使用＆＃34; sidekiq_mailer＆＃34;又：

class PersonMailer < ActionMailer::Base

  default from: "no-reply@myAwesomeProject.com"

  # Templates in "views/mailers/mailer_name/method_name.html.erb"
  default template_path: "mailers/#{self.name.underscore}"

  def send_email_new_user(user)
    @user = user
    mail(to: @user.email, subject: "You = <3")
  end

end

我这样打电话给我的邮件（在PersonController里面）：

PersonMailer.send_email_new_user(user).deliver

错误

现在让我们谈谈我的错误。在终端中运行bundle install后，我无法启动本地主机服务器（rails s）。总是我尝试它我收到以下错误：
