ExecJS and could not find a JavaScript runtime

I'm trying to use the Mongoid / Devise Rails 3.1 template (Mongoid and Devise), and I keep getting an error stating ExecJS cannot find a JavaScript runtime. Fair enough when I didn't have any installed, but I've tried installing Node.js, Mustang and the Ruby Racer, but nothing is working.

I could not find a JavaScript runtime. See sstephenson/ExecJS (GitHub) for a list of available runtimes (ExecJS::RuntimeUnavailable).

What do I need to do to get this working?

ruby-on-rails-3.1 execjs javascript

An alternative way is to just bundle without the gem group that contains the things you don't have.

So do:

bundle install --without assets

you don't have to modify the Gemfile at all, providing of course you are not doing asset chain stuff - which usually applies in non-development environments. Bundle will remember your '--without' setting in the .bundle/config file.

FYI, this fixed the problem for me... it's a pathing problem: http://forums.freebsd.org/showthread.php?t=35539
