OK - I had the same problem   I didn t want to use  config assets compile   true  - I had to add all of my  css files to the list in config environments production rb   config assets precompile     w  carts css     Then I had to create  and later delete  tmp restart txt  I consistently used the stylesheet link tag helper  so I found all the extra css files I needed to add with   find      -type f -o -type l    -exec grep stylesheet link tag     dev null

For all those who are reading this but do not have problem with application css and instead with their custom CSS classes e g  admin css  base css etc   Solution is to use as mentioned  bundle exec rake assets precompile   And in stylesheets references just reference application css   lt    stylesheet link tag     application    media   gt   all    gt    Since assets pipeline will precompile all of your stylesheets in application css  This also happens in development so using any other references is wrong when using assets pipeline

I was having the exact same error in my development environment  In the end all I needed to do in order to fix it was to add   config assets manifest   Rails root join  public assets     to my config environments development rb file and it fixed it  My final config in development related to assets looks like   config assets compress   false   config assets precompile     w bootstrap-alerts js   Lots of other space separated files config assets compile   false config assets digest   true config assets manifest   Rails root join  public assets   config assets debug   true

A quick fix for capistrano user is to put this line to Capfile    Uncomment if you are using Rails  asset pipeline load  deploy assets

if you think you followed everything good but still unlucky  just make sure you capistrano run touch tmp restart txt or equivalent at the end  I was in the unlucky list but now

I also had this issue  where trying to run in production without precompiling it would still throw not-precompiled errors  I had to change which line was commented application rb       If you precompile assets before deploying to production  use this line     Bundler require  Rails groups  assets   gt   w development test        If you want your assets lazily compiled in production  use this line   Bundler require  default   assets  Rails env

On heroku server  readonly filesystem    If you want runtime compilation of css  its not recommended but you can do it   make sure you have done settings like below -     inside config application rb config assets enabled   true config assets prefix   Rails root join  tmp assets   to s    If you are using sass then keep gem outside of asset group  gem  sass-rails      3 1 4     inside config environments production rb config assets compile   true

You probably have a syntax error in the css you are using   Run this command    bundle exec rake assets precompile RAILS ENV development --trace   It will give the exception  fixed that and you are all done   Thanks

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

Just another way to fix this up on Heroku  Make sure your Rakefile is committed and pushed

By default Rails assumes that you have your files precompiled in the production environment  if you want use live compiling  compile your assets during runtime  in production you must set the config assets compile to true     config environments production rb     config assets compile   true       You can use this option to fallback to Sprockets when you are using precompiled assets but there are any missing precompiled files   If config assets compile option is set to false and there are missing precompiled files you will get an  AssetNoPrecompiledError  indicating the name of the missing file

After all else failed     My solution was to change the layout file from    stylesheet link tag  reset-min    application    to    stylesheet link tag  application    And it worked   You can put the reset file inside the manifest

You will get better performance in production if you set config assets compile to false in production rb and precompile your assets   You can precompile with this rake task   bundle exec rake assets precompile   If you are using Capistrano  version 2 8 0 has a recipe to handle this at deploy time   For more info  see the  In Production  section of the Asset Pipeline Guide   http   guides rubyonrails org asset pipeline html

Here s the quick fix   If you re using capistrano do this add this to your deploy rb   after  deploy update code  do   run  cd   release path   RAILS ENV production rake assets precompile  end   cap deploy
