capistrano not working without rvm

Question

I've just changed my development machine from rvm to rbenv, but my production machine is still using rvm. Now when I try and deploy I get this error message:

cap deploy

Here is my deploy.rb

require 'bundler/capistrano'
require 'thinking_sphinx/deploy/capistrano'

set :application, "myapp"
set :repository,  "myuser@localhost:/home/myuser/myapp"

# Deployment options
set :deploy_to, "/home/remoteuser/myapp"
set :deploy_via, :copy

# Remote user info
set :user, "myuser"
set :use_sudo, false
default_run_options[:pty] = true

# Version control system 
set :scm, :git
set :branch, "master"

# Add RVM's lib directory to the load path.
$:.unshift(File.expand_path('./lib', ENV['rvm_path']))

# Load RVM's capistrano plugin.    
require "rvm/capistrano"
set :rvm_ruby_string, '1.9.2'
set :rvm_type, :user  # Don't use system-wide RVM

...

I don't want to have to change the server drastically and I feel that if I remove rvm and install ruby without a version control system it would be better but very disruptive.

Is there a way of fixing this error without change rvm on the server and rbenv on my dev box? If not should I just get rid of rvm and use rbenv on the server?

Answer 1

You need to wrap the rvm code in a test:

if ENV['rvm_path']
  $:.unshift(File.expand_path('./lib', ENV['rvm_path']))
  require "rvm/capistrano"
  set :rvm_ruby_string, '1.9.2'
  set :rvm_type, :user
end

And if you still require RVM for deployin on production:

• install RVM
• remove sourcing lines
• set export rvm_path=/path/to/rvm in ~/.bash_profile

or:

• clone git://github.com/wayneeseguin/rvm.git
• set export rvm_path=/path/to/rvm in ~/.bash_profile
