This error occurs whenever a functions signature is grabbed with jedi:get-in-function-call, and originates at line 103:

emacs-jedi/jediepcserver.py

Line 103 in b0764f4

params=[p.get_code().replace('\n', '') for p in call_def.params],

This prevents jedi-mode from doing any sort of function signature completion.

Package version is 20160425.2156. The relevant code in my .emacs file is

 (require 'jedi)                                                                                                                                                                                                   
 (setf jedi:complete-on-dot t)                                                                                                                        
 (unless (jedi:-env-server-command)                                                                                
      (jedi:install-server)))

I have uninstalled/reinstalled jedi-mode through the package manager several times, as well removing the server manually deleting the installation folder. The server has then always been reinstalled with jedi:install-server.

@sdilts sdilts changed the title from deferred error : (error "\"AttributeError(\\\"'Definition' object has no attribute 'get_code'\\\",)\"") to deferred error : (error ""AttributeError("'Definition' object has no attribute 'get_code' ",)"") Sep 28, 2017

I have a similar AttributeError, on a different attribute: (error "\"AttributeError(\\\"'module' object has no attribute 'defined_names'\\\",)\"")

I have the following package versions in my virtualenv:

$ pip freeze
epc==0.0.5
jedi==0.11.0
jediepcserver==0.2.7
parso==0.1.0
pkg-resources==0.0.0
sexpdata==0.0.3

and jedi version 20160425.2156

@sdilts I'm not calling anything explicitly, this keeps popping up in messages when I edit python files, even if I just open an empty one.

My eldoc-style call signature help recently stopped working. If I run jedi:get-in-function-call I get:

deferred error : (error "\"AttributeError(\\\"'Definition' object has no attribute 'get_code'\\\",)\"")

It seems defined_names is part of a depreated API that was dropped in jedi 0.11.0 (davidhalter/jedi@d6a04b2)

(This message is intended for newbies like me). I tried the solution of @albertodonato and @sdilts but my level in emacs and python was too low to make it work (I modified by hand line 103 105 and 179 of jediepcserver.py of the folder elpa/jedi-core/ + installing again everything).

The solution of @jrab89 was the winner: i installed in my real python (compared to the virtualenv one created by jedi.el) an older version of jedi: pip3 install jedi==0.10.2 (pip3 because I run python on mac OS which is a mess: https://docs.brew.sh/Homebrew-and-Python.html)

By the way, yes, jedi and jedi.el are two completely different "things".

Then an old-fashioned copy and replace of the two folders jedi/ jedi-0.10.2.dist-info/ located in the site-packages/ folder of my real python3 environment in the site-packages/ folder of the virtualenv created by jedi.el did the trick.

Good luck!
