I am studying RoR and I am setting this virtual machine to "deploy" RoR and I got stuck in the Node.js installation.
I am using Ubuntu 12.04 and I followed this step of this guide:
http://railsapps.github.com/installing-rails.html
Since Rails 3.1, a JavaScript runtime has been needed for development on Ubuntu Linux (it is not needed for Mac OS X or Windows). For development on Linux Ubuntu, it is best to install the Node.js server-side JavaScript environment:
$ sudo apt-get install nodejs
and set it in your $PATH.
What does it mean, "set to my $PATH"?
I've been searching for it on google in the last couple of hours and all solutions are different, for different problems and I get no simple answer for that. Can you give a little light here?
Thanks!
