Rails 5.1，Errno :: EMFILE：太多打开的文件 - getcwd

Question

在运行整个/ spec目录的过去几天，我开始看到这个错误。我怀疑它是否揭示了我的测试状态 - 它是随机发生的。我的预感是 Errno::EMFILE: Too many open files - getcwd # /Users/fred/.rvm/gems/ruby-2.4.1/gems/carrierwave-0.11.2/lib/carrierwave/sanitized_file.rb:115:in `expand_path' #

  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

堆栈跟踪始终相同。我无法在我的代码中明确地看到打开文件的位置。

我最近使用以下选项实现了DatabaseCleaner：

$urlRouterProvider.otherwise(function () {
    var items = window.localStorage.getItem('username');
    if (items === undefined || items === null || items.length === 0) {


        return '/app/login';


    }
    else {


        return '/app/search';


    }


});

Answer 1

他们将此问题与Carrierwave 0.5.8相关联。

post是从2012年3月14日开始的，所以肯定是过时的

  

我可以确认直到0.5.7的载波正常工作。只有0.5.8会导致此问题。我将在今晚晚些时候在carrierwave中打开一个问题。

但你有Carrierwave 0.11.2
