Ruby on rails 由于dalli导致unicorn运行时错误

Unicorn处于循环中，并显示以下错误：

独角兽错误

错误--：找不到dalli_存储的缓存存储适配器（无法 加载这样的文件--active_support/cache/dalli_store（运行时错误）

production.rb

config.cache_store = :dalli_store, "127.0.0.1:11211", { :namespace => "my-app", :expires_in => 3600 }

gemfile

gem 'dalli', '~>2.1.0', :git => "git://github.com/mperham/dalli.git"

我在rails控制台中进行了测试，dalli似乎没有问题

Loading production environment (Rails 3.2.8)
irb(main):001:0> Rails.cache.write("hello", "world")
=> true
irb(main):002:0> Rails.cache.read("hello")
=> "world"

irb(main):002:0> Rails.cache
=> #<ActiveSupport::Cache::DalliStore:0xabaefc8 @options={:namespace=>"my-app", :expires_in=>3600, :compress=>nil}, @raise_errors=false, @data=#<Dalli::Client:0xabaef00 @servers=["127.0.0.1:11211"], @options={:namespace=>"my-app", :expires_in=>3600, :compress=>nil}, @ring=#<Dalli::Ring:0xa2db0e0 @servers=[#<Dalli::Server:0xa2db158 @hostname="127.0.0.1", @port=11211, @weight=1, @fail_count=0, @down_at=nil, @last_down_at=nil, @options={:down_retry_delay=>1, :socket_timeout=>0.5, :socket_max_failures=>2, :socket_failure_delay=>0.01, :value_max_bytes=>1048576, :username=>nil, :password=>nil, :keepalive=>true, :namespace=>"my-app", :expires_in=>3600, :compress=>nil}, @sock=#<Dalli::Server::KSocket:fd 8>, @msg=nil, @pid=27069, @inprogress=false, @lock=#<Monitor:0xa2db0a4 @mon_owner=nil, @mon_count=0, @mon_mutex=#<Mutex:0xa2db07c>>, @version="1.4.2", @error=nil>], @continuum=nil, @failover=true>>>

加载生产环境（Rails 3.2.8）
irb（main）：001:0>Rails.cache.write（“你好”，“世界”）
=>正确
irb（main）：002:0>Rails.cache.read（“你好”）
=>“世界”
irb（主）：002:0>Rails.cache

任何帮助都将不胜感激。

我删除了bundler下载的Gemfile.lock和dalli gemspec文件（比如/path/to/app/shared/bundler/gems/ruby/1.8/specifications/dalli.gemspec），运行了“bundle install”，这很有帮助。

我也遇到了同样的问题，在我的例子中，这是由'rvm'引起的。

（我的设置是Phushion Passenger，Rails3，Memcached）

我用以下方法修复了它：

rvm all do gem install uuidtools

现在我的memcached统计数据显示：

希望这有帮助

谢谢。成功了。如何手动重启unicorn？手动重启unicorn是什么意思？

rvm all do gem install kgio
