È possibile trovare ulteriori dettagli su questo problema in questo Gist: https://gist.github.com/richardsondx/10092890 Ho notato che l'ambiente non è menzionato nel rake task anche se l'ho menzionato in production.rb. Si potrebbe contribuire a sovrascrivere il prefisso il comando con RAILS_ENV = produzione

ho cercato di sovrascrivere il compito di:

namespace :deploy do 

    namespace :assets do 
    task :precompile do 
     on roles(fetch(:assets_roles)) do 
     within release_path do 
      with rails_env: fetch(:rails_env) do 
      execute :rake, "assets:precompile RAILS_ENV=production" 
      end 
     end 
     end 
    end 
    end 
end 

Ma non sovrascriverlo.
