"Stack" is not found when coding Haskell in emacs

Question

While coding Haskell in emacs(stack installed with brew) on MacOS 10.12 I get the error:

Error while checking syntax automatically: (file-error "Searching for program" "no such file or directory" "stack")

My config file .emacs contains the following:

(require 'package)
add-to-list
'package-archives
'("melpa" . "http://melpa.org/packages/") t)
(package-initialize)
(package-refresh-contents)
(package-install 'intero)
(add-hook 'haskell-mode-hook 'intero-mode)

Running with emacs --debug-init gives no errors.

Does somebody know how to solve this?

1. issue M-x toggle-debug-on-error and try it again (--debug-init only breaks into debugger on startup). 2. Are you sure stack is in the path? Did you try running it from terminal? — Yuri Steinschreiber

@Yuri 1. Worked! I now get each time I change something the error: Company: An error occurred in auto-begin Symbol's function definition is void: haskell-completions-completion-at-point 2. It works in the terminal. However, I don't know how to verify if it's in the correct path — Janjaap Ree

Adding (add-to-list 'exec-path "/usr/local/bin/") to .emacs config file fixed the problem. Thanks @elethan — Janjaap Ree

I've managed to fix the problem by adding

(add-to-list 'exec-path "/usr/local/bin/")

to the .emacs config file.

I'd recommend the exec-path-from-shell library; I had similar issues on OS X and this solved them for me.

Once the library is installed, put the following in your .emacs:

(exec-path-from-shell-initialize)

If you ever run emacs from the shell, it may be worth inserting the following instead:

(when (memq window-system '(mac ns))
  (exec-path-from-shell-initialize))
