我按照thinking sphinx website上的说明使用延迟作业插件设置延迟增量。
所有似乎都安装正确，但是当我第一次'ts：dd'时，我明白了：
rake ts:dd --trace
** Invoke ts:dd (first_time)
** Invoke thinking_sphinx:delayed_delta (first_time)
** Invoke thinking_sphinx:app_env (first_time)
** Execute thinking_sphinx:app_env
** Execute thinking_sphinx:delayed_delta
rake aborted!

答案 0 :(得分：5)
对于延迟作业3，您需要安装一个后端gem，例如delayed_job_active_record用于activerecord后端。
