clojure cider on catalina The lein executable isn’t on your ‘exec-path’

I found these two links:

Clojure on emacs fails... & clojure isn't in your exec...

I'm unable to get cider to run on MacOS. I've been just using lein on the command line, but I would prefer to use cider.

I build a new project, like so:

lein new ec

open up core.clj

run Mx cider-jack-in

and I get:

The lein executable isn’t on your ‘exec-path’

I checked for the default in cider, and it is lein.

Is there any way to run cider on MacOS?

Solution

  • there are some macOS related problems with exec path detection for emacs.

    There is an emacs package, that should solve this issue: exec-path-from-shell.

    It used to help me when i was using macos (like 3 years ago, but i think it is still valid)

    Otherwise you can try to put an absolute path for lein (which lein in terminal) to cider-lein-command: M-x customize-group [ret] cider [ret] -> Cider lein command, that should also work.
