Emacs: installing jedi

Error (jedi): Failed to start Jedi EPC server.
*** You may need to run "M-x jedi:install-server". ***
This could solve the problem especially if you haven't run the command yet
since Jedi.el installation or update and if the server complains about
Python module imports.

by the command venv-workon I'll guess that you're using virtualenvwrapper.el.

jedi.el is sensitive to the variable python-shell-virtualenv-path which virtualenvwrapper.el sets globally. So you only need to set the variable python-shell-virtualenv-path to your virtualenv path.

Now, for your problem actually you need to update match the following variables.

;; Used by virtualenvwrapper.el
(setq venv-location (expand-file-name "~/.envs"))   ;; Change with the path to your virtualenvs
;; Used python-environment.el and by extend jedi.el
(setq python-environment-directory venv-location)

# Now things should work

M-x exec-path-from-shell-initialize

M-x jedi:install-server

Jedi should now be working

# Add Elpy to the .emacs
