I am fighting a few hours trying to configure PyCharm for debugging my app. I was looking for solution, but twisted seems to not be so popular and there is weak support. Below I put error log that i got.
/usr/local/bin/python3.4m -u /Applications/PyCharm CE.app/Contents/helpers/pydev/pydev_run_in_console.py 57276 57277 /usr/bin/twistd -y /Users/artur/projs/private/elanga-web/start_app.tac
Running /usr/bin/twistd
PyDev console: starting.
Traceback (most recent call last):

import _preamble
ImportError: No module named '_preamble'
During handling of the above exception, another exception occurred:

I will be grateful for an answer why there is no such module like _preamble
On OS X, /usr/bin/twistd is a version of Twisted installed into the system python. This is not python 3.4. The symptom you're seeing is not the missing _preamble module (which is in fact not supposed to be installed, which is why there is an except block around that import catching the exception) but rather that you have pointed python 3.4 at some random python 2 program.
If you want to run python 3.4, you need to create a python 3 environment with Twisted installed. Keep in mind that not all of Twisted is ported, so only a subset of APIs will be available to you. One of the things that is not ported to python 3 yet is the twistd command line, so there's no way to run twistd with python 3 yet.
