我的Sidekiq服务器突然不想再跑了，我无法解释自己为什么。这是错误消息：
undefined method `merge' for #<String:0x007f1ac9aa1848>
/home/deploy/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/sidekiq-4.1.4/lib/sidekiq/cli.rb:366:in `parse_config'

/home/deploy/.rbenv/versions/2.3.1/bin/sidekiq:23:in `load'
/home/deploy/.rbenv/versions/2.3.1/bin/sidekiq:23:in `<main>'
我使用以下命令启动它：
bundle exec sidekiq -e production -P /home/deploy/rails_app/shared/pids/sidekiq.pid -c 8
您可以在此处找到sidekiq.yml文件：http://codepaste.net/rujg15。 请帮忙:(
