Fail to use pdb module to debug LLDB python command module

I write a python script for cusotm command. And I want to make some debug for my script. So I try to use the pdb module.

import pdb; pdb.set_trace()

However, something goes wrong:

module ‘lldb_editline’ has no attribute ‘set_completer_delims’

Is there anything I can do? Thanks you.

environment: ubuntu22.04, lldb 14.0.0
