啟動targetcli時遭遇ImportError: cannot import name ALUATargetPortGroup故障

targetcli是一個iSCSI配置管理工具，該工具簡單易用，可以直接替換scsi-target-utils。滿心歡喜的裝上它，正準(zhǔn)備一睹為快，就杯具了。報錯ImportError: cannot import name ALUATargetPortGroup。下面就這針對這個錯誤的解決方案。

一、故障現(xiàn)象

當(dāng)前環(huán)境
[root@centos7-router ~]# more /etc/redhat-release 
CentOS Linux release 7.2.1511 (Core)

安裝targetcli工具包
# yum install targetcli

故障現(xiàn)象
[root@centos7-router ~]# targetcli
Traceback (most recent call last):
 File "/usr/bin/targetcli", line 24, in <module>
  from targetcli import UIRoot  ### Author : Leshami
 File "/usr/lib/python2.7/site-packages/targetcli/__init__.py", line 18, in <module>
  from .ui_root import UIRoot  ### Blog : http://blog.csdn.net/leshami
 File "/usr/lib/python2.7/site-packages/targetcli/ui_root.py", line 30, in <module>
  from .ui_backstore import complete_path, UIBackstores
 File "/usr/lib/python2.7/site-packages/targetcli/ui_backstore.py", line 29, in <module>
  from rtslib_fb import ALUATargetPortGroup
ImportError: cannot import name ALUATargetPortGroup

二、解決方案

從上面的錯誤提示可知，python文件有問題。于是驗(yàn)證一下python是否已正確安裝
[root@centos7-router ~]# python
Python 2.7.5 (default, Nov 20 2015, 02:00:19) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 

python可以正常工作，繼續(xù)google，原來是缺少python-rtslib這個包。

[root@centos7-router ~]# yum install python-rtslib -y

再次執(zhí)行成功
[root@centos7-router ~]# targetcli
targetcli shell version 2.1.fb46

GENERALITIES
============
This is a shell in which you can create, delete and configure
configuration objects.

The available commands depend on the current path or target
path you want to run a command in: different path have
different sets of available commands, i.e. a path pointing at
an iscsi target will not have the same availaible commands as,
say, a path pointing at a storage object.

The prompt that starts each command line indicates your
current path. Alternatively (useful if the prompt displays
an abbreviated path to save space), you can run the
pwd command to display the complete current path.

Navigating the tree is done using the cd command. Without
any argument, cd will present you wil the full objects
tree. Just use arrows to select the destination path, and
enter will get you there. Please try help cd for navigation
tips.

COMMAND SYNTAX
==============
Commands are built using the following syntax:

[TARGET_PATH] COMMAND_NAME [OPTIONS]

The TARGET_PATH indicates the path to run the command from.
If ommited, the command will be run from your current path.

The OPTIONS depend on the command. Please use help
COMMAND to get more information.


AVAILABLE COMMANDS
==================
The following commands are available in the
current path:

 - bookmarks action [bookmark] 
 - cd [path] 
 - clearconfig [confirm] 
 - exit 
 - get [group] [parameter...] 
 - help [topic] 
 - ls [path] [depth] 
 - pwd 
 - refresh 
 - restoreconfig [savefile] [clear_existing] 
 - saveconfig [savefile] 
 - sessions [action] [sid] 
 - set [group] [parameter=value...] 
 - status 
 - version
