Issue with Deploying a Rails app on VPS - cannot load such file -- unicorn/launcher

Rails
#1

I am trying to deploy a rails application to a digitalocean VPS droplet.
I
have the following setup Ruby on Rails on Ubuntu 12.10 (Nginx +
Unicorn). I
have installed Ruby ruby-2.0.0-p247 and rails Rails 4.0.0 via rvm but
when
I try to restart Unicorn I get the following error.

/usr/local/rvm/rubies/ruby-2.0.0-p247/lib/ruby/site_ruby/2.0.0/rubygems
/core_ext/kernel_require.rb:45:in require': cannot load such file -- unicorn/launcher (LoadError) from /usr/local/rvm/rubies/ruby-2.0.0-p247/lib/ruby/site_ruby/2.0.0/rubygems /core_ext/kernel_require.rb:45:inrequire’
from /usr/bin/unicorn:3:in `’

Could it be because if my GEM_HOME and GEM_PATH are different?

$GEM_PATH
/usr/local/rvm/gems/ruby-2.0.0-p247:/usr/local/rvm
/gems/[email protected]

$GEM_HOME
/usr/local/rvm/gems/ruby-2.0.0-p247

Any help would very much appreciated.

Have you tried re-installing(bundle install) the gem under the
gemset/ruby you’re currently using?
it seems that unicorn was not installed correctly or is not installed at
all.
