Unknown Cop Error

[estiens]

When I run from the command line everything is fine

$ which rubocop
/Users/estiens/.rbenv/shims/rubocop

$ rubocop -v
0.57.1

$ /Users/estiens/.rbenv/shims/rubocop --auto-correct
Inspecting 5 files
.....
5 files inspected, no offenses detected

$ rubocop --auto-correct
Inspecting 5 files
.....
5 files inspected, no offenses detected

However inside Atom I get

and it won't run. This is true whether I use rubocop or /Users/estiens/.rbenv/shims/rubocop as my command

[estiens]

(if I change my global rbenv settings to the version of ruby with the upgraded version of rubocop, it works fine -- so it appears even though it is using the shim, it is pulling from global rbenv version rather than local version)
