rspec tests always show failure using terminal-notifier-guard

Question

Although all my specs show as passing in my terminal, the notification ALWAYS shows they failed. Its a pretty simple setup, but do i have something misconfigured? How can i troubleshoot this?

Gemfile

group :development do
  gem 'guard'
  gem 'guard-rspec'
  gem 'rspec'
  gem 'terminal-notifier-guard'
end

Guardfile

notification :terminal_notifier
guard :rspec, all_after_pass: true, all_on_start: true do
  # ...
end

Answer 1

The problem was guard was not configured to run rspec using bundle exec

guard :rspec, cmd: 'bundle exec rspec' do
  ...
end
