Compiled assets are not found in production mode run locally

I have a strange behaviour with compiled assets when running a simple draft app locally:

RAILS_ENV=production rake assets:precompile

The aove command generated some css and js with finger printed values:

i.e. application-43dcf2bdff355d2c3053e2aade23881a.css

application-c67be452a576850d0c11559f908180e3.js

etc.

Run in production:

rails s -e production

There are no CSS fiound !

When observing the html source:

There are the following errors in the console as well:

Any idea ? What is wrong here ? Why Rails 4 didn’t see my assets ? It is just a simpe app with one generated scaffold for posts, nothing special, no additional configurations added . really weird.

This is strange. This issue can occur for individual css and js files but
application.css and application.js should be added by default.

For other files you have to add config.assets.precompile +=
%w(filename.css).

I found the way to make it work:

add/modify the following line in environments/production.rb:

config.serve_static_assets = true

config.assets.compile = true

Then run again

$ RAILS_ENV rake assets:precompile

$ rails s -e production

And it works.

The default is for .serve_static_assets to be false, since normally in production one lets apache, nginx or a CDN handle static assets
