Netmiko netgear_prosafe运行报错re.error: unbalanced parenthesis at position 0

阅读《NetDevOps入门与实践》章节 10.1.3 netmiko
使用脚本: ssh_iosxr.py

由于手头没有Cisco IOS XR设备,也懒得在自己的eve-ng平台模拟~~
所以直接改了改脚本,使用手头有的Cisco IOS-XE、Cisco NX-OS、H3C和Netgear设备进行测试.
前3种设备测试修改后的脚本均很顺畅,单单测试Netgear时,遇到了问题,报错如下:

$ python3 ssh_netgear_by_Ross.py -H NetgearIP -u Username

搜索引擎查了一下,发目前Stack Overflow上找到一例同样使用Netgear交换机报类似错误的帖子,但是没有解决方案:
why-i-am-getting-re-error-unbalanced-parenthesis-at-position-0-error-here

然后去了netmiko的issue页面尝试使用”netgear”关键字查了查,点开第一个内容,找到解决方法:

随后在我的笔记本上找到该文件,改之,解决
/usr/local/lib/python3.9/site-packages/netmiko/netgear/netgear_prosafe_ssh.py
上面是我电脑上该文件的路径,根据操作系统不同、Python的安装方式不同,该路径可能略有不同.

最后,上使用netmiko成功配置Netgear交换机的截图:
