Q:

ActionView::Template::Error (application.css isn't precompiled):

Ive developed several apps on heroku before and never ran into this error:
ActionView::Template::Error (application.css isn't precompiled):
My latest push didn't even have a change to the application.css file.. Whats going on here?
Ive seen articles saying change a line in production.rb to:
# Don't fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = true

But wont that slow everything down? Why is this error suddenly happening? Whats the best way to fix it?
Edit:
I should note its working in development just fine.

A:

Run rake assets:precompile:all in your development environment. Ensure that it does not give you an error and that it creates public/assets/application.css. If it does give you an error, resolving it should resolve the problem on Heroku.
