How to debug “python -m module_name” using pudb

Question

I have the following python call:

python -m module_name

The file structure is as below:

module_name
    __init__.py
    __main__.py

Previously, I debug using pudb for signle python program without -m in the following way:

python -m pudb.run file_name.py

Considering this, I tried the following command but got error:

python -m pudb.run -m module_name

Error messages:

Usage: run.py [options] SCRIPT-TO-RUN [SCRIPT-ARGUMENTS]
run.py: error: no such option: -m

Is there any solution for debug 'python -m module_name' using pudb?

Answer 1

Not an exact solution to your problem, but if you cannot find a way to do it like that, you can instead import and start pudb in your module, for example in the __main__.py file:

import pudb 
pu.db

# Rest of your module code

And then run it with

python -m module_name

It will automatically start in pudb that way.

Answer 2

this is supported now. see this merged PR
