在 Golang 中调用 targetcli 命令进行交互操作时发现报了如下的错误：
Go
Copy
exit status 1
exit status 1: Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/configshell_fb/shell.py", line 893, in run_interactive
old_completer = readline.get_completer()
NameError: name 'readline' is not defined
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/usr/bin/targetcli", line 121, in <module>
main()
File "/usr/bin/targetcli", line 111, in main
shell.run_interactive()
File "/usr/lib/python3/dist-packages/configshell_fb/shell.py", line 899, in run_interactive
readline.set_completer(old_completer)
NameError: name 'readline' is not defined
网上查了下资料应该是 python config shell 的 bug 导致在交互命令下 readline 不能正常的工作
具体的 pr

Commit82f79eb 下面升级下 config shel
$pip3 list 查看 python 的依赖的 package
configshell-fb (1.1.20)
果然 1.1.20 是有问题的
下面对 configshell 进行升级
Go
Copy
$pip3 install --upgrade configshell-fb
