ruby-on-rails – sidekiq不会使用Redistogo在heroku上生成sidek

在heroku上部署后,我的应用程序崩溃,我收到以下错误堆栈跟踪：

首先,sidekiq在我的本地机器上正常工作.我正在使用heroku的REDISTOGO作为redis,在本地制作中,sidekiq已经被正确地指向REDISTOGO并且运行正常.

其次,根据堆栈跟踪,特别是这行没有这样的文件或目录@ rb_sysopen – /app/tmp/pids/sidekiq.pid;它导致我认为,由于某些原因,在heroku上运行时,sidekiq.pid文件不能正确生成.在本地环境中,每当我在app / tmp / pids /目录中启动应用程序时,都会生成sidekiq.pid文件,并且每次分配一个不同的pid号码.我猜,当在heroku上运行时,sidekiq试图从这个文件中读取,但找不到它.

以下是我的Procfile中的内容：

web: bundle exec rails server
worker: bundle exec sidekiq -C config/sidekiq.yml

这里是我的config / sidekiq.yml中的内容

---
:verbose: true
:pidfile: ./tmp/pids/sidekiq.pid
:concurrency: 25
# Set timeout to 8 on Heroku,longer if you manage your own systems.
:timeout: 8
:queues:
  - carrierwave

这里是我的sidekiq.rb的内容

Sidekiq.configure_server do |config|
  config.redis = { :url => ENV['REDISTOGO_URL'],:namespace => "mynamespece"}
end

Sidekiq.configure_client do |config|
    config.redis = { :url => ENV['REDISTOGO_URL'],:namespace => "mynamespece"}
end

更新1：

我正在使用carrierwave和carrierwave-backgrounder与sidekiq同步.
