Hello,

Same problem for me :

File "/usr/local/lib/python3.7/site-packages/netmiko/_textfsm/_clitable.py", line 34, in <module> import copyable_regex_object ModuleNotFoundError: No module named 'copyable_regex_object'

I hadn't this problem before the update.

As a workaround, you can downgrade the textfsm module to version 0.4.1 with the following command:

sudo pip3 install --upgrade textfsm==0.4.1

[carlmontanari]

1292 should fix this. Going to close but please reopen w/ stack trace if dev branch (of netmiko) doesnt fix this. Or as @thearch1tech stated you can just downgrade TextFSM if you dont want to install dev branch of netmiko!

[ktbyers]

Yes, the Netmiko-textfsm issue is fixed in the Netmiko develop branch.

Alternatively, you can pip install textfsm==0.4.1. The underlying issue is that TextFSM changed their library structure which affected some things Netmiko is doing and Netmiko had only recently implemented a fix for this.

I will try to push out a new release of Netmiko in the next few days.

Thanks @ktbyers @carlniger @thearch1tech

[ktbyers]

I released Netmiko 2.4.1 today that fixes this issue.
