手工点一下升级，BT挂了。如何修复？

SSH中提示如下错误。

[root@mycentos ~]# /etc/init.d/bt start
Starting Bt-Panel... failed
------------------------------------------------------
Traceback (most recent call last):
  File "main.py", line 14, in <module>
    from tools import CloseLogs
ImportError: cannot import name CloseLogs
------------------------------------------------------
Error: BT-Panel service startup failed.

yum install -y wget && wget -O install.sh http://download.bt.cn/install/install.sh && sh install.sh

直接再安装一次，好了。汗
