このプログラムEM :: Synchrony#syncを使用すると、「ルートファイバー」FiberErrorが発生します。
require 'em-synchrony' ## v1.0.0
require 'em-hiredis' ## v0.1.0
module EventMachine
module Hiredis
class Client
def self.connect(host = 'localhost', port = 6379)
conn = new(host, port)
EM::Synchrony.sync conn.connect
conn
end
alias :old_method_missing :method_missing
def method_missing(sym, *args)
EM::Synchrony.sync old_method_missing(sym, *args)
end
end
end
end
EventMachine.synchrony do
redis = EM::Hiredis.connect
redis.set('foo', 'bar')
puts redis.get('foo')
EM.stop
end
は、私は、これは深く混乱見つけるこの

のように死にます。なぜそれはうまくいかず、私は間違っているのですか?もしそうなら、私はどうしたら違うことができますか?私が何かを見ていない限り、em-synchrony READMEによればこれは正当なものです。
