Intellij/pycharm Can't Debug Python Modules

I use PyCharm/IntelliJ community editions from a wile to write and debug Python scripts, but now I'm trying to debug a Python module, and PyCharm does a wrong command line instruct

Solution 1:

There is another way to make it work.You can write a python script to run your module.Then just configure PyCharm to run this script.

import sys
import os
import runpy
path = os.path.dirname(sys.modules[__name__].__file__)
path = os.path.join(path, '..')
sys.path.insert(0, path)
runpy.run_module('<your module name>', run_name="__main__",alter_sys=True)

Then the debugger works.

Solution 2:

In PyCharm 2019.1 (professional), I'm able to select run as module option under configurations, as below

Solution 3:

I found it easiest to create a bootstrap file (debuglaunch.py) with the following contents.

from {package} import {file with __main__}

if __name__ == '__main__':
    {file with __main__}.main()

For example, to launch locustio in the pycharm debugger, I created debuglaunch.py like this:

from locust import main

if__name__== '__main__':
    main.main()

And configured pycharm as follows.

NOTE: I found I was not able to break into the debugger unless I added a breakpoint on main.main() . That may be specific to locustio, however.

Solution 4:

The problem is already fixed since PyCharm 4.5.2. See corresponding issue in PyCharm tracker: https://youtrack.jetbrains.com/issue/PY-15230
