Okay. This is a new problem caused by a gem update. Calling bundle update breaks my rails application. Here are the gems that changed:
# Gemfile.lock
-
I've found that the updated gems, which have in their instructions to change application.css to application.css.scss, don't recognize just 'application' as a parameter for a scss file for stylesheet_link_tag. You need to change:
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
to this:
<%= stylesheet_link_tag 'application.css.scss', media: 'all', 'data-turbolinks-track' => true %>
This will allow you to work with the latest gems.
