If 'rubocop' is not a typo you can use command-not-found to lookup the package that contains it, like this:
    cnf rubocop

bundle install

bundle install --path vendor/bundle

gem install rubocop -v 0.63.1

sudo gem install rubocop -v 0.63.1

bundle exec rubocop -a

bundle exec rubocop -x app/controllers/concerns/anything.rb
