Clojure Mode - `nrepl-jack-in' gives error

Clojure Mode - `nrepl-jack-in' gives error

[Thorsten Jolitz]

Hi List, 

[this was posted on the clojure list too, but on 2nd thought it looks
more like and Emacs than and Clojure question]

I just installed lein2 and can start 'lein2 repl' successfully on the
command-line. 'lein repl' works too, since I defined an alias in my
.bashrc. 

After installing packages clojure-mode and nrepl in Emacs, I get this
error when trying `nrepl-jack-in':

,-------------------------------------------------------------------------
| error in process sentinel: Could not start nREPL server: /bin/bash: Line
| 1: lein: Command not found.
`-------------------------------------------------------------------------

I'm on Archlinx with

#+begin_src emacs-lisp
 (emacs-version)
#+end_src

#+results:
: GNU Emacs 24.3.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.10.7)
:  of 2014-01-28 on var-lib-archbuild-extra-x86_64-juergen

I googled some related sites and it seems it might be an Emacs (exec-) path
problem, but a reboot did not help. I don't find any reference to
leiningen/clojure/nrepl in Emacs exec-path nor in '$ echo $PATH', but
things work on the command-line, but not from Emacs.

You mean CIDER, right?  Otherwise please do install CIDER,
this is the replacement for nrepl:

https://github.com/clojure-emacs/cider

No, I had never heard of it ... thanks for the tip! So I was on the
wrong (i.e. outdated) track wrt to Clojure & Emacs, no wonder it did not
work ...

Since we're at it, here is my setup:

clojure-mode / cider / company-mode

all them installed from ELPA.

And some useful settings:

(require 'cider)
(require 'company)
(require 'company-cider)
(setq nrepl-hide-special-buffers t)
(setq cider-repl-pop-to-buffer-on-connect nil)
(setq cider-popup-stacktraces nil)
(setq cider-repl-popup-stacktraces t)
(setq org-babel-clojure-backend 'cider)
(add-hook 'clojure-mode-hook 'turn-on-orgstruct)
(eval-after-load 'company '(add-to-list 'company-backends 'company-cider))

Enjoy!

Installed and copied 1 to 1 into my init.el (except orgstruct because
for obvious reasons I rather use outline-minor-mode/outshine) - and it
works like a charm now.

Thanks a lot!
