I'm trying to get Emacs to start ipython from Anaconda.
I have two systems which are not identical so figured setting symbolic links in ~/bin/ipython as I have ~/bin/ pre-pended to my $PATH would do the trick. It works on one system no problem but on the other no joy.
My ~/.emacs.d/settings/python-settings.el (sourced from ~/.emacs.d/init.el) has...
;; PYTHON CONFIGURATION
;; --------------------------------------
(elpy-enable)
;; Set ipython as the default interpreter
(setq python-shell-interpreter "~/bin/ipython"
python-shell-interpreter-interactive-args "-i --simple-prompt")
;; use flycheck not flymake with elpy
(when (require 'flycheck nil t)
(setq elpy-modules (delq 'elpy-module-flymake elpy-modules))
(add-hook 'elpy-mode-hook 'flycheck-mode))
;; Try to add pylint rules
https://emacs.stackexchange.com/a/41048/10100
(add-hook 'python-mode-hook
(lambda ()
(setq flycheck-python-pylint-executable "~/.local/bin/pylint")
(setq flycheck-pylintrc "~/.emacs.d/settings/.pylintrc")))
;; enable autopep8 formatting on save
(require 'py-autopep8)
(add-hook 'elpy-mode-hook 'py-autopep8-enable-on-save)
When I try to run M-x run-python I get...

..and yet at a terminal it is found and works...

It looks like the ~ is escaped and not interpreted correctly so I've tried with both an explicit path to the target of the symbolic link with...
(setq python-shell-interpreter "/home/slackline@mywork.com/share/anaconda3/bin/ipython"
python-shell-interpreter-interactive-args "-i --simple-prompt")
...which results in...
/usr/bin/emacs: /home/slackline\@mywork.com/share/anaconda3/bin/ipython: No such file or directory
Process Python exited abnormally with code 127
...and the following under *Warnings*...
Warning (python): Python shell prompts cannot be detected.
If your emacs session hangs when starting python shells
recover with ‘keyboard-quit’ and then try fixing the
interactive flag for your interpreter by adjusting the
‘python-shell-interpreter-interactive-arg’ or add regexps
matching shell prompts in the directory-local friendly vars:
+ ‘python-shell-prompt-regexp’
+ ‘python-shell-prompt-block-regexp’
+ ‘python-shell-prompt-output-regexp’
Or alternatively in:
+ ‘python-shell-prompt-input-regexps’
+ ‘python-shell-prompt-output-regexps’
...which is a bit closer but iPython isn't starting under Emacs. I suspect it may have something to do with the weird @ in the path of my home directory but am unsure why "~/bin/ipython" is not correctly recognised under Emacs when it is from the command line.
Any suggestions as to whats going on and how to resolve them would be very welcome.
