Rails, rake does not work

Question

I\'ve been trying to use Rails and when I use rake, I get this error. Any suggestions on which run time should I use?

Answer 1

I have installed the gem therubyracer, execjs, mustang but nothing worked.

On my linux (ubuntu) the command

sudo apt-get install nodejs

did the job finally for me.
