rope: TypeError: cannot concatenate 'str' and 'NoneType' objects #826

Closed jmercouris closed 8 years ago

jmercouris commented 8 years ago

Really Doesn't like my piece of code, crashes on it every time when I'm writing

journalfile.write(next ...)

debug.txt

jorgenschaefer commented 8 years ago

Hello, and thanks for the report! I'm afraid that debug.txt link is not leading anywhere – what output do you get from Elpy when it crashes? :-)

jmercouris commented 8 years ago

Hey, I'm sorry that's all the details I could get, it would just open up in a new buffer and had that output, is there some log that I can check? If I recreate the crash, what should I do?

Usually, when Elpy encounters a problem, it pops up a debug window with more information.

What exactly do you mean with "crashes"? Does your Emacs actually crash, as in, terminate?

jmercouris commented 8 years ago

Emacs did not terminate. What I did when it crashed was open up a scratch buffer, copy all the text from the debug window and yank it into the scratch buffer, that is what I attached. Is there another log I should look for, or a different way to pull the data?

Ah, there we go … when I first tried to download that debug.txt, the link was broken.

This is a bug in Rope I'm afraid. As a workaround, you can either set elpy-disable-backend-error-display to t to avoid this display, or try using Jedi instead of Rope. I'll report this upstream.

Thanks for the report!

Actually, looks like this is the same error as #805 – I'll close this issue so we can keep the discussion in one spot. In any case, it was good to have this report. Thank you!

jmercouris commented 8 years ago

No problem! Good luck!
