HerokuでResqueを実行するためにconfig.ruを設定するには？

Question

私はconfig.ruファイルに次のようなエラーがあり、その下にHerokuがクラッシュします。

require ::File.expand_path('../config/environment', __FILE__) 
run Picasa::Application 

require 'resque/server' 
run Rack::URLMap.new \ 
    "/" => Picasa::Application, 
    "/resque" => Resque::Server.new

Answer 1

あなたはあなたが必要とするすべてはあなたのroutes.rbをファイルに

mount Resque::Server.new, :at => "/resque" 

であり、その場合にはRailsの3.0.9を実行しているように見えます。
