安装MEF Center时，运行最后一步命令./install.sh后，显示如下：

check path success 

init log success 

install pre check success 

start to prepare working dir 

prepare working dir success 

start to prepare certs 

install failed, start to clear environment 

start to clear docker image 

clear docker image success 

start to clear node label 

clear node label success 

start to clear install dir 

clear install dir success 

start to clear lock 

clear mef-center lock success 

clear environment success 

install MEF center failed

应该如何解决？
