Installation and use of the command 'virtualenv' was only needed in py2 and py2 is no longer suported by searx. In py3 the command is replaced by 'python -m venv'. Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>

;;; .dir-locals.el

;;
|
|
;; If you get ``*** EPC Error ***`` (even after a jedi:install-server) in your
|
|
;; emacs session, mostly you have jedi-mode enabled but the python enviroment is
|
|
;; missed. The python environment has to be next to the
|
|
;; ``<repo>/.dir-locals.el`` in::
|
|
;;
|
|
;; ./local/py3
|
|
;;
|
|
;; In Emacs, some buffer locals are referencing the project environment:
|
|
;;
|
|
;; - prj-root --> <repo>/
|
|
;; - python-environment-directory --> <repo>/local
|
|
;; - python-environment-default-root-name --> py3
|
|
;; - python-shell-virtualenv-root --> <repo>/local/py3
|
|
;; When this variable is set with the path of the virtualenv to use,
|
|
;; `process-environment' and `exec-path' get proper values in order to run
|
|
;; shells inside the specified virtualenv, example::
|
|
;; (setq python-shell-virtualenv-root "/path/to/env/")
|
|
;;
|
|
;; To setup such an environment build target 'pyenv' or 'pyenvinstall'::
|
|
;;
|
|
;; $ make pyenvinstall
|
|
;;
|
|
;; Alternatively create the virtualenv, source it and install jedi + epc
|
|
;; (required by `emacs-jedi <https://tkf.github.io/emacs-jedi>`_)::
|
|
;;
|
|
;; $ python -m venv ./local/py3
|
|
;; ...
|
|
;; $ source ./local/py3/bin/activate
|
|
;; (py3)$ # now install into the activated 'py3' environment ..
|
|
;; (py3)$ pip install jedi epc
|
