title: ExecJS runtime error
body: <p>I have installed nodejs on ubuntu 12.04 server and I want to know why I have problems when compiling assets, when I go to the console <code>rails c</code> I run this</p>
  
  <pre><code>ExecJS::Runtimes.best_available=&gt; #&lt;ExecJS::ExternalRuntime:0x0000000118cc88
  @binary="nodejs",
  @command=["nodejs", "node"],
  @deprecated=false,
  @encoding="UTF-8",
  @name="Node.js (V8)",
  @runner_path= "/home/bonsai/.rvm/gems/ruby-1.9.3-p392@rails3.2/gems/execjs-1.4.0/lib/execjs/support/node_runner.js",
  </code></pre>
  
  <p>@test_args=nil,
      @test_match=nil></p>
  
  <p>And of course I can run <code>node</code> or <code>nodejs</code> commands, what can be wrong, this is the error after trying to compile assets</p>
