Intellij/Pycharm can't debug Python modules

Question

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 instruction parsing, causing an execution error, or maybe I'm making a bad configuration.

This is my run/debug configuration:

And this is executed when I run the module (no problems here):

/usr/bin/python3.4 -m histraw

But when I debug, this is the output in the IntelliJ console:

/usr/bin/python3.4 -m /opt/apps/pycharm/helpers/pydev/pydevd.py --multiproc --client 127.0.0.1 --port 57851 --file histraw
/usr/bin/python3.4: Error while finding spec for '/opt/apps/pycharm/helpers/pydev/pydevd.py' (<class 'ImportError'>: No module named '/opt/apps/pycharm/helpers/pydev/pydevd')

Process finished with exit code 1

As you can see, the parameters are wrong parsed, and after -m option a IntelliJ debug script is passed before the module name.

I also tried just put -m histraw in the Script field, but doesn't work, that field is only to put Python script paths, not modules.

Any ideas?

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.
