did you prepend “bundle exec” to your call to “rails server” ?

try sudo apt-get install nodejs

I am usung Linux Mint 17 and RVM so I created an issue on https://github.com/wayneeseguin/rvm/issues/3153

exec bash -l helped

That issue does not seem to have much to do with the javascript
runtime problem that you asked about.

Yes you are right.
I tried ruby -v and rails -v after I posted my problem here and I got messages that I don’t have them installed aldough I installed the so I serched help about RVM.

And that command solved my problems.
