Setting Exec-Path When Using Zsh and Tmux

Question

I am using Emacs 25.2 with Zsh; and I have added the following to my init.el file to set both the Path and exec-path.

;; Set shell path
(defun set-shell-path ()
  (let ((shell-path (shell-command-to-string "$SHELL -i -c 'echo $PATH'")))
    (setenv "PATH" shell-path)
    (setq exec-path (split-string shell-path path-separator))))

(when (display-graphic-p)
    (set-shell-path))

When the above executes it results in the error:

("compaudit" "133" "command not found" "getent compaudit" "open terminal failed" ...)

My zshrc includes the following:

autoload -U compinit && compinit -i
...
# Launch Tmux.
if command -v tmux &> /dev/null; then
  [[ ! $TERM =~ dumb ]] && [[ ! $TERM =~ screen ]] && [ -z $TMUX ] && exec tmux -u
fi
...

Suggestions on how I can/should solve this error are appreciated? Thanks.

Whatever compinit is, apparently it fails if there's no terminal. Since you're running this shell command inside emacs, there's not going to be a terminal.

Also, exec-path is already initialized from your PATH when emacs starts up; none of this should be necessary.
