rvm - can I make a version of ruby installed via rvm the system default (I thought it would be)?

Question

I always have a hard time with rvm so sorry if this has been answered - I have to work with rvm infrequently so some of the ideas don't fully set in.

On my server (a fresh droplet at Digital Ocean) i installed rvm as the deploy user, via:

$\curl -L https://get.rvm.io | bash -s stable
$ source /home/deploy/.rvm/scripts/rvm
$rvm install 1.9.3-p392
$rvm use 1.9.3 --default

If I login as root, I can't see this ruby. Can I make this the system ruby or did I make a mistake? For example, I tried installing the nginx component of passenger via:

root$ passenger-install-nginx-module

but get

root$ passenger-install-nginx-module: command not found

and

root$ which ruby # nothing

Am I supposed to just add the add the path of /home/deploy/.rvm/rubies/ruby-1.9.3-p392/bin/ as an environment variable (I doubt that)? Or have I totally messed this up (which is ok since we don't have anything on droplet)? Is this the recommended way to manage rubies?

thx in advance

Answer 1

you must load your environtment into folder before. Run this command in terminal:

       $ rvm use 1.9.3

Then "ruby -v" must work.
