无法在RedHat中安装/识别Javascript运行时（对于Rails 3.1）

Question

Trying to setup a production deployment on a dedicated box running RedHat (64bit):

# cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 5.6 (Tikanga)

For the life of me, I can't get a Javascript Runtime installed and/or recognized by my Rails 3.1.0rc6 app.

I've done a gem install of execjs, therubyracer, libv8, and mustang ... still get this error after restarting:

ActionView::Template::Error (Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes.
  (in /var/www/demo-setup/releases/20110825184931/app/assets/javascripts/demos.js.coffee)):

Also installed node.js but still get this error.

Any ideas?

I don't know what the solution is, but maybe this will help:

The error is being thrown from ExecJS here . If therubyracer gem is installed, then it should be detected by the line require "v8" here .

Can you require "v8" successfully from irb ? If so, then that tells you that Rails is being run on a different set of gems somehow. Are you using rvm?
