一、故障现象
当前环境 [root@centos7-router~]#more/etc/redhat-release CentOSLinuxrelease7.2.1511(Core) 安装targetcli工具包 #yuminstalltargetcli 故障现象 [root@centos7-router~]#targetcli Traceback(mostrecentcalllast): File"/usr/bin/targetcli",line24,infromtargetcliimportUIRoot###Author:Leshami File"/usr/lib/python2.7/site-packages/targetcli/__init__.py",line18,in from.ui_rootimportUIRoot###Blog:http://blog.csdn.net/leshami File"/usr/lib/python2.7/site-packages/targetcli/ui_root.py",line30,in from.ui_backstoreimportcomplete_path,UIBackstores File"/usr/lib/python2.7/site-packages/targetcli/ui_backstore.py",line29,in fromrtslib_fbimportALUATargetPortGroup ImportError:cannotimportnameALUATargetPortGroup
