启动队列时Ruby on Rails Resque db连接错误

Question

当我尝试通过rake resque：work QUEUE ='*'启动resque队列时，出现“数据库配置未指定适配器”错误。 数据库连接还可以，因为它可以获取数据并显示在索引页中。 和...我可以在〜/ resque / overview中看到排队的任务，但是它没有执行。

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

根据错误消息的内容，您可以验证database.yml文件的外观吗？ 每个环境是否都有关联的适配器（例如sqlite3，mysql2等）？
