So, I'm trying to use ack from emacs. I've tried setting the path correctly in the following manner

(setenv "PATH"
  (concat "/home/davor/bin/bin:"
          (getenv "PATH")))

(setq exec-path (append exec-path '("~/bin/bin" "/usr/local/bin")))

This gives me the following path

ELISP> exec-path 
  ("/usr/bin" "/bin" "/usr/sbin" "/sbin" 
  "/Applications/Emacs.app/Contents/MacOS/bin-x86_64-10_10" 
  "/Applications/Emacs.app/Contents/MacOS/libexec-x86_64-10_10" 
  "/Applications/Emacs.app/Contents/MacOS/libexec" 
  "/Applications/Emacs.app/Contents/MacOS/bin" "~/bin/bin" 
  "/usr/local/bin")

When I try to run ack, I get this error

zsh:1: command not found: ack

It should be able to find it, though.

➜  ~ ls -la /usr/local/bin/|grep ack
lrwxr-xr-x    1 davorb  admin    26 Aug 20 11:15 ack -> ../Cellar/ack/2.24/bin/ack

What am I missing?

  • you should be adding /usr/local/Cellar/ack/2.24/bin/ to PATH variable.. – junnu Oct 19 '18 at 10:43
  • @junnu isn't it enough with the symlink that's in place? – davorb Oct 19 '18 at 13:05

    yeah it should be enough.. could you try adding /usr/local/bin (where symlink is located) or /usr/local/Cellar/ack/2.24/bin/ (where binary is located) to PATH variable and check once.. you added the symlink path to exec-path but not to PATH variable. you could confirm whether the path is set correctly or not with echo $PATH – junnu Oct 19 '18 at 17:03

    You are starting zsh (maybe via term) in emacs to run ack? In that case you have to add /usr/local/bin via (setenv "PATH" (concat (getenv "PATH") ":/usr/local/bin")). – Tobias Oct 19 '18 at 17:05
