Ahoy Gem导致没有路线匹配[GET]“/ undefined”

Question

安装Ahoy Gem后添加
ahoy.trackAll(); application.js到我的/undefined，我的申请会不断重定向到SQL (0.3ms) INSERT INTO `ahoy_events` (`id`, `visit_id`, `name`, `properties`, `time`) VALUES (x'438ffd6f7d4c4291876441fa2b5dcdf0', x'61671132b25b4f169a54ece65dc524b3', '$view', '{\"url\":\"http://localhost:3000/\",\"title\":\"Title\",\"page\":\"/\"}', '2015-08-10 20:12:57') (30.7ms) COMMIT Completed 200 OK in 161ms (Views: 0.2ms | ActiveRecord: 68.8ms) Started GET "/undefined" for ::1 at 2015-08-10 16:12:59 -0400 ActionController::RoutingError (No route matches [GET] "/undefined"): 。我已经尝试卸载并重新创建数据库，但没有运气。

这是服务器日志。
