I made a basic rails app with a simple pages controller with an index function and when I load the page I get:
ActionView::Template::Error (application.css i
I ran into this error message today and wanted to post the resolution to my particular my case. It turns out that my problem was that one of my css files was missing a closing brace and this was causing the file to not be compiled. It may be harder to notice this if you have an automated process that sets everything up (including the asset precompile) for your production environment.
