Capistrano error on rake assets:precompile:all but still working (using RVM) - capistrano

Question

I've made a new Rails 3.2 application. When i deploy it with Capistrano, I get an error when compiling assets. But the assets ARE compiled, and the application deployed as it should.
On the server I've installed RVM systemwide and then created:
User: skolemapicture (added to group rvm)
Deploy folder: /home/skolemapicture/site
.rvmrc in /home/skolemapicture/site/.rvmrc
My deploy.rb config looks like this (omitted lines that have nothing to do with the problem)
set :application, "skolemapicture"
set :deploy_to , "/home/skolemapicture/site"
set :user , "skolemapicture"
set :use_sudo , false
ssh_options[:forward_agent] = true
require "bundler/capistrano"
require "rvm/capistrano"
set(:ruby_version) { '1.9.3' }
set(:rvm_ruby_string) { "#{ruby_version}##{application}" }
set(:rvm_path) { "/usr/local/rvm" }
set(:rvm_type) { :system }
namespace :deploy do
task :precompile, :role => :app do
run "cd #{release_path}/ && bundle exec rake assets:precompile"
end
end
after "deploy:finalize_update", "deploy:precompile"
The error i get at "cap deploy" is:
* 2013-02-13 10:36:21 executing `deploy:precompile'
* executing "cd /home/skolemapicture/site/releases/20130213093619/ && bundle exec rake assets:precompile"
servers: ["web01.mapicture.com"]
[web01.mapicture.com] executing command
*** [err :: web01.mapicture.com] /usr/local/rvm/rubies/ruby-1.9.3-p374/bin/ruby /home/skolemapicture/site/shared/bundle/ruby/1.9.1/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets
*** [err :: web01.mapicture.com]
But the assets ARE compiled. So why this error?

Answer 1

It is probably actually precompiling the assets successfully with your custom deploy:precompile task.
It is failing on the capistrano default assets:precompile task.
You will notice that the failed command is
/usr/local/rvm/rubies/ruby-1.9.3-p374/bin/ruby /home/skolemapicture/site/shared/bundle/ruby/1.9.1/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets
not your custom precompile task:
cd #{release_path}/ && bundle exec rake assets:precompile
Try removing your deploy:precompile task and adding
load 'deploy/assets'
to your Capfile if it is not already there.
If that doesn't fix it can you post your entire Capfile and deploy.rb?
