我有两台服务器，我从一台服务器（A）复制代码，然后尝试在另一台服务器上运行（B）。
我在A的所有工人都工作正常。当我从B运行工作人员时，我收到了这个错误：
NameError: uninitialized constant FeedRefresherFetcher
这里是引发错误的工作人员代码：
class FeedRefresherScheduler
include Sidekiq::Worker
def perform
Feed.select(:id, :feed_url).find_in_batches(batch_size: 5000) do |feeds|
arguments = feeds.map do |feed|
values = feed.attributes.values
values
end
Sidekiq::Client.push_bulk(
'args' => arguments,
'class' => 'FeedRefresherFetcher',
'queue' => 'feed_refresher_fetcher',
'retry' => false
)
end
end
end

另请注意，我的workers目录中没有定义名为FeedRefresherFetcher的工作程序。但是，代码再次与服务器A相同，而在服务器A上则相同。
我对sidekiq工人不太了解。知道什么可能是错的吗？
