Hello Everyone,
Can anyone please describe the relationship of javascript-runtime to Ruby on Rails? In Mac OSX, I do not get this error, but in Linux for every new project generated by "rails new", I get:
play$ rails s//.rvm/gems/ruby-2.0.0-p0/gems/execjs-1.4.0/lib/execjs/runtimes.rb:51:in `autodetect': Could not find a JavaScript runtime. See https://github.com/sstephenson/execjs for a list of available runtimes.
I know the solution; either install therubyracer or nodejs gems. But I am not sure I understand fully why it works. If I install this in a production environment server, I do not need either one of these. And my browser definitely interprets javascript built in. So how does this fit in to everything? Is my premise incorrect? Thank you.
Peter
