我已經爲rails項目安裝了slanger（和redis）。每個rails實例都關閉。Slanger：Eventmachine port exception
我運行redis-server，它工作正常。但後來我跑：
slanger --app_key MyPusherApiKey --secret MyPusherSecret
，並提出了下一個異常：
我的目錄/紅寶石/紅寶石-2.2.3/lib中/紅寶石/寶石/ 2.2.0 /寶石/eventmachine-1.0.9.1/lib/eventmachine.rb:534:in`start_tcp_server'：無受體（端口在使用或需要root權限）（RuntimeError）
from my-directory/rubies/ruby-2.2.3/lib/ruby/gems/2.2.0/gems/eventmachine-1.0.9.1/lib/eventmachine.rb:534:in `start_server'
from my-directory/rubies/ruby-2.2.3/lib/ruby/gems/2.2.0/gems/em-websocket-0.5.1/lib/em-websocket/websocket.rb:46:in `run'
from my-directory/.rvm/rubies/ruby-2.2.3/lib/ruby/gems/2.2.0/gems/em-websocket-0.5.1/lib/em-websocket/websocket.rb:39:in `block in start'
from my-directory/.rvm/rubies/ruby-2.2.3/lib/ruby/gems/2.2.0/gems/eventmachine-1.0.9.1/lib/eventmachine.rb:170:in `call'
from my-directory/.rvm/rubies/ruby-2.2.3/lib/ruby/gems/2.2.0/gems/eventmachine-1.0.9.1/lib/eventmachine.rb:170:in `run'
我認爲，如果端口有人在用，我可以改變這樣的：
slanger --app_key MyPusherApiKey --secret MyPusherSecret -a 0.0.0.0:3646
但我仍然得到同樣的錯誤。有任何想法嗎？
