Question

I have a problem with Capistrano deploying to a server with RVM and gemsets

executing `deploy:assets:precompile'
* executing "cd /var/app/releases/20111229233555 && rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile"
*** [err ::] rake aborted!
*** [err ::] Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes.
*** [deploy:update_code] rolling back
failed: "rvm_path=$HOME/.rvm/ $HOME/.rvm/bin/rvm-shell '1.9.2@mygemset' -c 'cd /var/app/releases/20111229234715 && rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile'"

This is my Capfile

  $:.unshift(File.expand_path('./lib', ENV['rvm_path']))
  require 'rvm/capistrano'
  set :rvm_bin_path, "$HOME/.rvm/bin"
  set :rvm_ruby_string, '1.9.2@mygemset'
  set :rvm_type, :user
  load 'deploy/assets'

When I log in as the very same user which is used by Capistrano the failing command is executed without any problems.

It seems that Capistrano is using some other environment.

Here is my ~/.rvmrc file:

   rvm_gemset_create_on_use_flag=1 rvm_trust_rvmrcs_flag=1

Is there a way how to check which ruby and gemset is used at the execution time?

node.js is and V8 are installed on the system, and all needed gems are in Gemfile:

here is my rvm info:

   ruby:
    interpreter:  "ruby"
    version:      "1.9.2p290"
    date:         "2011-07-09"
    platform:     "x86_64-linux"
    patchlevel:   "2011-07-09 revision 32553"
    full_version: "ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux]"

  homes:
    gem:          "/home/capistrano/.rvm/gems/ruby-1.9.2-p290@mygemset"
    ruby:         "/home/capistrano/.rvm/rubies/ruby-1.9.2-p290"

  binaries:
    ruby:         "/home/capistrano/.rvm/rubies/ruby-1.9.2-p290/bin/ruby"
    irb:          "/home/capistrano/.rvm/rubies/ruby-1.9.2-p290/bin/irb"
    gem:          "/home/capistrano/.rvm/rubies/ruby-1.9.2-p290/bin/gem"
    rake:         "/home/capistrano/.rvm/gems/ruby-1.9.2-p290@mygemset/bin/rake"

Answer 1

setting up PATH in the deploy.rb solved this issue:

default_environment['PATH'] = "/usr/local/bin:/usr/bin:/bin:/opt/bin:$PATH"

it’s a Gentoo distribution and the PATH var seems to be empty when using cap deploy, so I copied the content of server PATH and now it works
