播放要求在Akka代码上隐式应用，即使它已导入

Question

使用play 2.4.x.我的代码如下所示：

import play.api.Play.current

val linkedinParse = Akka.system.actorOf(Props[LinkedinParse], name = "linkedinParse") 

Play会产生编译错误：

You do not have an implicit Application in scope. If you want to bring the 
current running Application into context, just add import play.api.Play.current

即使我有导入
