在 routes.rb 中添加 mount Resque::Server.new, :at => "/resque"
rake routes 出错，但路由解析是正常的，web 界面也可以访问。求解决
DELETE /plans/:id(.:format) {:action=>"destroy", :controller=>"plans"}
/resque {:to=>#<Sinatra::ShowExceptions:0x0000000566fcd8 @user1=#<Rack::Head:0x0000000566f8a0 @user2=#<Rack::NullLogger:0x0000000566f580 @user3=#<Rack::Protection::FrameOptions:0x00000005652bd8 @user4=#<Rack::Protection::IPSpoofing:0x00000005651e40 @user5=#<Rack::Protection::JsonCsrf:0x00000005650ab8 @user6=#<Rack::Protection::PathTraversal:0x000000056466d0 @user7=#<Rack::Protection::XSSHeader:0x00000005629468 @user8=#<Resque::Server:0x000000055b12b0 @user9=:layout, @user10=nil, @user11=#<Tilt::Cache:0x000000055b1800 @user12={}>>, @options={:reaction=>:default_reaction, :logging=>true, :message=>"Forbidden", :encryptor=>Digest::SHA1, :session_key=>"rack.session", :status=>403, :allow_empty_referrer=>true, :xss_mode=>:block, :except=>[:escaped_params, :session_hijacking, :remote_token]}>, @options={:reaction=>:default_reaction, :logging=>true, :message=>"Forbidden", :encryptor=>Digest::SHA1, :session_key=>"rack.session", :status=>403, :allow_empty_referrer=>true, :except=>[:escaped_params, :session_hijacking, :remote_token]}>, @options={:reaction=>:default_reaction, :logging=>true, :message=>"Forbidden", :encryptor=>Digest::SHA1, :session_key=>"rack.session", :status=>403, :allow_empty_referrer=>true, :except=>[:escaped_params, :session_hijacking, :remote_token]}>, @options={:reaction=>:default_reaction, :logging=>true, :message=>"Forbidden", :encryptor=>Digest::SHA1, :session_key=>"rack.session", :status=>403, :allow_empty_referrer=>true, :except=>[:escaped_params, :session_hijacking, :remote_token]}>, @options={:reaction=>:default_reaction, :logging=>true, :message=>"Forbidden", :encryptor=>Digest::SHA1, :session_key=>"rack.session", :status=>403, :allow_empty_referrer=>true, :xss_mode=>:block, :frame_options=>:sameorigin, :except=>[:escaped_params, :session_hijacking, :remote_token]}>>>, @template=#<ERB:0x00000005670908 @user19=nil, @user20="#coding:US-ASCII\n_erbout = ''; _erbout.concat \"<!DOCTYPE html>\\n<html>\\n<head>\\n <meta http-equiv=\\\"Content-Type\\\" content=\\\"text/html; charset=utf-8\\\"/>\\n
换一种方式试下，去掉 routes 中的配置 mount Resque::Server.new, :at => "/resque" 在 config.ru 中加， run Rack::URLMap.new \ "/" => APP::Application, "/resque" => Resque::Server.new
多谢指点
不过在我的环境中，APP::Application 还是会报错 最后是注释掉原生的： #run Edm::Application 添加： run Rack::URLMap.new "/" => Edm::Application, "/resque" => Resque::Server.new
大功告成
