ImportError: cannot import name 'with_argparser_and_unknown_args' from 'cmd2'

[mdhuynh]

Hi, after installing mptcpanalyzer I cannot use it because of import error. I already check tshark 3.2.3 and python version is 3.8.10.

The full error when call mptcpanalyzer:

root@ubuntu:~# mptcpanalyzer 
Traceback (most recent call last):
  File "/root/.local/bin/mptcpanalyzer", line 5, in <module>
    from mptcpanalyzer.cli import main

    from cmd2 import with_argparser, with_argparser_and_unknown_args, with_category, argparse_completer
ImportError: cannot import name 'with_argparser_and_unknown_args' from 'cmd2' (/root/.local/lib/python3.8/site-packages/cmd2/__init__.py)

thanks for the report, I need to do a new release as cmd2 has evolved a lot.

Thank you!

I've merged some changes in master, could you try installing/running it with poetry ? poetry install once in the mptcpanalyzer folder.
