--trace) rake stderr: nothing written 

i have noticed if remove line *= require styles in application.css file, deploys, not solution looking for. assets/stylesheets file-structure shown below:

running rake assets:precompile compiles assets locally, in dev environment. during deployment capistrano task cap env_name deploy:assets:precompile being invoked (as can see on top of backtrace), on it's part invokes rake assets:precompile on remote server. asset precompilation in development environment ignores syntax errors. try running rails_env=production rake assets:precompile --trace locally find , fix errors.
