AttributeError thrown upon every autocompletion trigger, when file contains a certain import about deoplete-jedi HOT 5 CLOSED

@bradst Hi,

I do not yet know the cause of the error.
but, Now neovim stable version is 0.1.3. Could you upgrade it?

Also, What are you using neovim/python-client?

from deoplete-jedi.

@zchee No problem. I've just upgraded neovim and python-client to latest git. neovim is now 0.1.3 (git HEAD 5330aa1) and python-client is now 0.1.7 (git HEAD 7af000e). The exception is still being thrown with the new version, exact same traceback.

@bradst We've been finding that a lot of the issues with deoplete-jedi is stemming from Jedi and different Python versions. Take a look at this issue to get up to speed on what I'm talking about: #21

We're currently hashing out a fix for most of the Python version issues. You can try out this branch to see if your issue goes away: https://github.com/tweekmonster/deoplete-jedi/tree/server

I'm currently on that branch and am able to do the Decimal completion without errors. You can also help us hash out issues with that branch 😄

@tweekmonster I just tried your branch. No exceptions are thrown, but from decimal import Decimal still causes auto-completion not to work.

I just did some digging and figured it out. The decimal module tries to use the native _decimal module and falls back to _pydecimal on ImportError. Apparently the native module depends on an external library called mpdecimal, which I didn't have installed, so Python was falling back on the pure Python implementation. It seems like Jedi wasn't able to follow the fallback so it choked when trying to access the native module, or something similar. Installing mpdecimal fixed the issue.

Thanks guys, I'll report this upstream to Jedi. Keep up the good work! 😃
