Mac系统下Lean工具执行lean up 后访问3001端口控制台报goroute的错误

关于这个错误，我在论坛上找到相应的说明，但是提问时间是在2016年的0.5.0版本。但是真不知道怎么解决，因为我使用的是0.21.0版本。

一、我使用的lean cli工具的版本是最新的0.21.0

  NAME:
 lean - Command line to manage and deploy LeanCloud apps

USAGE:
   lean [global options] command [command options] [arguments...]

VERSION:
   0.21.0

二、关于错误的描述

希望能帮忙解决一下，我找不到具体是哪边的引起的错误。

不好意思，真是抱歉。之前的错误发现原因了，是我这边交接的代码被删了部分代码造成的错误，是我这边的原因。很感谢提供帮助
