Emacs says "RuboCop not installed"

[oystersauce8]

Emacs is unable to find rubocop. My workstation uses rbenv.
I installed by doing gem install rubocop and
M-x package-install rubocop
M-x package-install rbenv

I'm using this workaround for now

(require 'rubocop)
(setq rubocop-check-command "/Users/redacted/.rbenv/shims/rubocop --format emacs")
(defun rubocop-ensure-installed () )

Any ideas ....

Same here, emacs 26 and rubocop 0.56

Emacs has its own exec-path and likely the rubocop executable is not on it. You can either extend the exec-path manually or install https://github.com/purcell/exec-path-from-shell

Yeah, I fixed it with:
(exec-path-from-shell-copy-env "GEM_PATH")

and the:

 $ rvm get head
 $ rvm use .
 $ gem install rubocop
 $ rubocop --auto-gen-config

inside the eshell.
