Carmen-rails undefined method "-"

Using carmen-rails to generate a country select element in my billing address form.

 country_select(:card, :country, {priority: ['United States', 'Canada']}, id: 'country')

The above usage causes the following error:

 NoMethodError: undefined method `-' for {:priority=>["United States", "Canada"]}:Hash

I have tried leaving out the priority option but the issues remains.

Solution

  • The issue was the result of having other gems installed.

    I had installed country-select gem version 1.1.1

    To resolve the issue I just had to remove the gem.

    gem uninstall country-select
