It also shows:

ActionView::Template::Error (The asset "landingherodrink.jpeg" is not present in the asset pipeline.).

It is my hero image and it is located at assets/images/

In Rails 5+, make sure you have specified the file extension.

Ie.:

<%= image_tag 'logo.jpg' %>

instead of:

<%= image_tag 'logo' %>

I'm a bit too late but just had the same issue and fixed it just by changing my image extension from .jpeg to .jpg and of course changing it also in the code.
