当我尝试通过rake resque:work QUEUE='*'启动 resque 队列时， 我收到“数据库配置未指定适配器”错误。我猜数据库连接没问题，因为它可以获取数据并显示在索引页面中。并且......我可以在 ~/resque/overview 中看到排队的任务，但它没有执行。
完整的错误消息是：
Initializing connection to redis...
Done (port = 6392)!
Configuring resque sheduler...
Resque scheduler configured
rake aborted!
database configuration does not specify adapter
