Rails 5.1，Errno :: EMFILE：太多打开的文件 - getcwd
问题描述：
在我运行我的整个/ spec目录时，我在过去几天开始看到这个错误。我怀疑它揭示了我的测试状态 - 它是随机发生的。我的直觉是它可能是rails_helper.rb中的配置问题。Rails 5.1，Errno :: EMFILE：太多打开的文件 - getcwd
Errno::EMFILE:
Too many open files - getcwd

堆栈跟踪总是相同的。我无法在我的代码中明确地看到任何地方正在打开文件。
我最近实施DatabaseCleaner使用下列选项：
config.use_transactional_fixtures = false
config.before(:each) do
Sidekiq::Worker.clear_all
end
config.before(:suite) do
DatabaseCleaner.clean_with(:truncation)
RedisCache.new.flushdb
end
config.before(:each) do
DatabaseCleaner.strategy = :transaction
end
config.before(:each) do
DatabaseCleaner.start
end
config.after(:each) do
DatabaseCleaner.clean
end

他们有这个问题，Carrierwave 0.5.8连接。
的post为14 /三月/ 2012，因此可以肯定的是过时的
我可以证实，carrierwave直到0.5.7正常工作。只有0.5.8导致这个问题。今晚晚些时候我将在carrierwave上发布一个问题。
但是你有Carrierwave 0.11.2
