You just need to get libv8, for OS with Brew just do:

brew install v8

Answer 2

i use this gems on Dreamhost with Rails 3.1 for the Asset Pipeline

group :assets do
  gem 'execjs'
  gem 'therubyracer', :platforms => :ruby
  gem 'johnson'
  gem 'sass-rails', "  ~> 3.1.0"
  gem 'coffee-rails', "~> 3.1.0"
  gem 'uglifier'
end

therubyracer as precompiler, and johnson as runtime.

This work for me in 2 Rails 3.1 apps hosted by Dreamhost.

Answer 3

I'm in dreamhost shared server.

I installed nodejs without using root/sudo. On the server:

#download node js (check last version from web)
$ wget http://nodejs.org/dist/v0.8.16/node-v0.8.16-linux-x86.tar.gz
#untar
$ tar xzf node-v0.8.16-linux-x86.tar.gz

Finnaly add its path to the deploy.rb, adding the following line (some more paths are added in this case):

default_environment["PATH"] = ":/home/myUser/soft/node-v0.8.16-linux-x86/bin:/home/myUser/.gems/bin:/usr/lib/ruby/gems/1.8/bin/:$PATH"

You are done
