3;; If you get ``*** EPC Error ***`` (even after a jedi:install-server) in your
4;; emacs session, mostly you have jedi-mode enabled but the python enviroment is
5;; missed. The python environment has to be next to the
6;; ``<repo>/.dir-locals.el`` in::
7;;
8;; ./local/py3
9;;
10;; In Emacs, some buffer locals are referencing the project environment:
11;;
12;; - prj-root --> <repo>/
13;; - python-environment-directory --> <repo>/local
14;; - python-environment-default-root-name --> py3
15;; - python-shell-virtualenv-root --> <repo>/local/py3
16;; When this variable is set with the path of the virtualenv to use,
17;; `process-environment' and `exec-path' get proper values in order to run
18;; shells inside the specified virtualenv, example::
19;; (setq python-shell-virtualenv-root "/path/to/env/")
20;;
21;; To setup such an environment build target 'pyenv' or 'pyenvinstall'::
22;;
23;; $ make pyenvinstall
24;;
25;; Alternatively create the virtualenv, source it and install jedi + epc
26;; (required by `emacs-jedi <https://tkf.github.io/emacs-jedi>`_)::
27;;
28;; $ python -m venv ./local/py3
29;; ...
30;; $ source ./local/py3/bin/activate
31;; (py3)$ # now install into the activated 'py3' environment ..
32;; (py3)$ pip install jedi epc
33;; ...
34;;
35;; Here is what also I found useful to add to my .emacs::
36;;
37;; (global-set-key [f6] 'flycheck-mode)
38;; (add-hook 'python-mode-hook 'my:python-mode-hook)
39;;
40;; (defun my:python-mode-hook ()
