Getting 'Cannot use module name 'service.py' in imports' error in the refactoring module

[swedishmike]

When I try to do the first part of the Large module smell exercise I get the following error:

The steps I'm trying to do is:

• Select the following two lines

  Episode = namedtuple('Episode', 'title link pubdate show_id')
  episode_data = {}

• Right-click
• Select 'Refactor / Move'
• Change the filename to service.py
• Click 'Refactor'

I'm not sure if I'm doing it the wrong way or if it might have something do do with my OS and/or version of PyCharm.

I'm running version 2018.2 on Xubuntu 16.04.

Hi Mike,

That is weird. I just tried this from scratch on a new project, same version of PyCharm (but on macOS) and it worked fine. Is there already a file named service.py or something installed in the environment that is a package called service?

Hi Michael,

I'm a black belt in weird computer behavior... ;)

Thanks for getting back to me - I can't find anything else in the environment but I'll create a new venv, just in case, and see if that helps.

There is of course the empty service.py that's in the directory when I clone the repo from here - I can try and delete that one and try again?

Cheers, Mike

Yes, that is it probably. Try deleting the service.py file.

That didn't resolve it - however, if I marked the 'smelly_podcast' directory as 'sources root' it works.

Many thanks for getting back to me - sometimes a bit of feedback is all that's needed to push me in the right direction. ;)

You're welcome. It's interesting that it had to do with "sources root". Thanks for digging that one up!

Same problem here. The refactoring move to service.py is prevented "cannot move module", until the folder containing both files is made a source root. Perhaps it would help to mention this in the video.

[mikeckennedy]

Hi @hewettp You're right about that sources root, depending on how you've opened the project you're editing. I'll add some info about this to the readme.
