[Inactive]Rails Precomple Css

[genfren]

Hi I keep getting this error

 

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

 

But I've put this two lines on config/environments/production.rb

config.assets.compile = true

config.assets.precompile += ['layout.css']

 

 

which should prcompile or complie all.

 

What can I do?
